**Title: A Comprehensive Guide to Configuring Emails for Office 365 and Odoo**

In today’s digital landscape, effective communication is crucial for businesses. Email remains one of the primary tools for communication, and integrating email services with business management software can enhance productivity and streamline operations. This article provides a detailed guide on how to configure emails to work with Office 365 and Odoo, ensuring that your organization can leverage the full potential of both platforms.

### Understanding the Importance of Integration

Odoo is a powerful open-source ERP (Enterprise Resource Planning) software that helps businesses manage various functions, including sales, inventory, and customer relationship management. Office 365, on the other hand, is a cloud-based suite of productivity tools that includes Outlook for email management. Integrating these two platforms allows for seamless communication, better data management, and improved collaboration among team members.

### Step-by-Step Configuration Guide

#### Step 1: Prepare Your Office 365 Account

Before you begin the integration process, ensure that you have an active Office 365 account. You will need administrative access to configure the necessary settings.

**Log in to your Office 365 Admin Center.**
**Navigate to the Exchange Admin Center.** This is where you will manage your email settings.
**Create a new user or use an existing one** that will be used for Odoo email configuration.

#### Step 2: Configure SMTP Settings in Office 365

To allow Odoo to send emails through Office 365, you need to configure the SMTP settings:

**Access the SMTP settings** in the Exchange Admin Center.
**Note the SMTP server address** (usually `smtp.office365.com`) and the port number (typically `587` for TLS).
**Ensure that the user account you created has the necessary permissions** to send emails.

#### Step 3: Set Up Odoo Email Configuration

Now that you have your Office 365 SMTP settings, you can configure Odoo to use these settings:

**Description:** A name for your mail server (e.g., Office 365).
**SMTP Server:** Enter `smtp.office365.com`.
**SMTP Port:** Enter `587`.
**Connection Security:** Select `TLS`.
**Username:** Enter the email address of the Office 365 account you created.
**Password:** Enter the password for the Office 365 account.

**Log in to your Odoo instance.**
**Navigate to the Settings module.**
**Under the Email section, select 'Outgoing Mail Servers.'**
**Click on 'Create' to add a new mail server.**
**Fill in the required fields:**
**Test the connection** to ensure that Odoo can communicate with the Office 365 SMTP server. If successful, save the configuration.

#### Step 4: Configure Incoming Mail (Optional)

If you want Odoo to receive emails as well, you can set up incoming mail servers:

**Description:** A name for your incoming mail server.
**Server Type:** Select `IMAP`.
**IMAP Server:** Use `outlook.office365.com`.
**Port:** Use `993` for SSL.
**Username and Password:** Use the same credentials as before.

**In the Odoo Settings, navigate to 'Incoming Mail Servers.'**
**Click on 'Create' and fill in the details:**
**Test the connection** and save the settings.

### Conclusion

Integrating Office 365 with Odoo can significantly enhance your business's communication capabilities. By following the steps outlined in this guide, you can ensure that your email system is configured correctly, allowing for efficient management of communications directly from your Odoo platform. This integration not only streamlines processes but also fosters better collaboration among team members, ultimately contributing to the success of your organization.

How to Configure Emails to Work with Office 365 and Odoo

30/03/2018 in Guides

This article is written for Office 365 Business subscribers who use the software as their internal and external mailing system. When your business is growing, you can start facing a mess in your mailbox. This indicates that you need to integrate your mailing system with ERP or CRM, so you can continue to use your favorite mail client. Then, all communications will be synced in a structured way into ERP/CRM for managing sales, tasks, support tickets, and more.

In this guide, learn how to configure emails to work seamlessly with Office 365 and Odoo. Utilize the Odoo Outlook for bidirectional communication, access Office 365 emails in Odoo, and vice versa. Optimize the Odoo SMTP server for reliable email delivery. Configure incoming emails in Odoo to handle customer queries efficiently. Customize Odoo’s email settings for a professional brand image and streamlined communication. Boost productivity and collaboration with this integration.

As an A–Z guide, we have provided you with a full set of instructions on how to configure your Office 365 Exchange to work with the Odoo ERP system. This guide was written with the goal to be an A-Z guide. If you find that this article is not complete enough or something is unclear, please leave your comments down below and we will correct these instructions and add clarifications to it.

Prerequisites

1. Assumption is that you are already a user of the Office 365 Business subscription that includes Exchange Server. E.g. “Office 365 Business Premium”.

2. You are already using mailing features from Office 365. Meaning you are not a new Office 365 subscriber. If you just purchased a subscription and haven’t configured anything yet, you first need to perform an initial setup by following the official Microsoft guide. It is especially important that you already have properly configured your custom domain. This Microsoft guide can help you with this.

3. People executing the steps below need to have Administrative access (Role: Global Administrator) to https://www.office.com. That is needed in order to create new users and groups on the Portal.

4. According to official Odoo documentation, You can use an Office 365 server if you run Odoo on-premise. Office 365 SMTP relays are not compatible with Odoo Online or Odoo.sh.

For Odoo Online or Odoo.sh or at instances where it is not possible to use 25 port or without a static IP address you can configure it by following article.

If all above preconditions are already fulfilled, then you can go ahead with next steps.

Configuring Outgoing mail Server in Office 365 as Relay Server

Principle of Operation

In this section, you will learn how to configure Office 365 to act like a relay server.

Why is it needed?

Odoo ERP is trying to operate as a relay server. Meaning that it is used as an intermediate layer to send emails from ANY mail address to ANY mail address. For example, after this mail configuration Odoo will be able to send emails from any email (for example somename@anydomain.com)

A little bit of clarification on why Odoo acts like this

Let’s imagine that you are getting an email from a potential lead to the address hello@company.com. Imagine that potential lead’s email address is john@example.com. Odoo ERP catches this email and creates a new Opportunity in the CRM Pipeline. And after Odoo creates it – it needs to send automatic emails to all followers, to inform everybody about the new Opportunity. As it is now implemented in Odoo ERP, the email will attempt to send FROM the email of the lead (e.g. john@example.com) and not from some generic email like erp@company.com. The reason why Odoo is doing it is to make sure that this email will be beautifully displayed as belonging to a real person and not to look like an automatic notification from ERP. And obviously when you respond to the person through Odoo CRM, your lead will also see that email is coming from realperson@company.com instead of some generic email erp@company.com. So the intention of Odoo is clear – they want to ensure all messages from ERP are personal and do not look like an automatic notification. But that gives additional headache relating to the mailing system configuration.

Configuring of a SMTP relay connector

The configuration of the outgoing mail server is based on the following documentation.

Login with your Global Admin user account to https://admin.microsoft.com and click on the “Admin centers -> Exchange” menu in the left panel

In the Opened Window click on the section “Mail flow -> Connectors”

Click the “Add a connector” on the opened page to add a new connector.
On the first screen with mail flow scenario, select the following values and click “Next”

From = “Your organization’s email server”

To = “Office 365”

Give a name to the connector. E.g. “OdooMail”. All checkboxes should be checked (default behavior). And click Next

Select checkbox to verify allowed senders by IP address and add IP addresses of all your Odoo ERP instances. That is a type of whitelist. Office 365 will trust messages sent from those IP addresses as safe.

After clicking “Create Connector” you should get the following screen with an already created connector

Configuring of a Anti-spam thread policy

Go back to Admin center click on the “Admin centers -> Security” menu in the left panel.

In the Opened Window move by following path “Policies & rules -> Threat policies -> Anti-spam -> Connection filter policy (Default)” and click on “Edit connection filter policy”

Add to “Always allow messages from the following IP addresses or addresses range” field IP addresses of all your Odoo ERP instances and click on “Save”.

Configuring of a Domain DNS records

You need to make sure that your domain has required DNS records. For this go back to Admin center and move by following path: “Settings -> Domains -> Your Domain -> DNS records”

We are interested in MX and SPF records. Check that the MX record looks like following structure:

<subdomain(optional)>-<second level domain(SLD)>-<top level domain (TDL)>.mail.protection.outlook.com

Example: contoso-com.mail.protection.outlook.com (domain with replaced dots to dash before .mail.protection.outlook.com).

If the MX DNS record does not match with mentioned structures, you should add them by the Admin panel of your domain provider.

Check that SPF record contain IP addresses of all your Odoo ERP instances and looks like following structure:

v=spf1 ip4:<your_ip> ip4:<your_other_ip(optional)> include:spf.protection.outlook.com ~all

If the SPF DNS record does not match with mentioned structures, you should add them by the Admin panel of your domain provider.

IMPORTANT!

If you are trying to integrate Office 365 emails with Amazon EC2, you will need to follow this article additionally. The reason why you need this – Amazon has additional protection to prevent spammers to send emails from their servers. So you have to explicitly request from them allowance to do that.

Configuring Catchall Email in Office 365

Principle of Operation

In this section, you will learn how to create a special mail address in Office 365 that will collect emails sent to unknown receivers (meaning no User exists in Office 365).

Why is it needed?

In Odoo ERP it is possible to configure multiple Sales Teams, Projects and etc. Any objects you want. For example, you may want to have a Sales Team with the name “Initial Processing Team”. That sales team should process leads that are received to the email address “hello@company.com”. Also, you may want to have separate Sales Teams which will be responsible for processing emails sent to addresses “asia-sales@company.com” and “europe-sales@company.com” or more.

You may configure as many email addresses as you want and obviously those email addresses will not be real emails in your Office 365 Portal.

So to avoid lots of manipulations in the Office 365 Portal when you are adding something new in Odoo ERP (new project, new sales team and etc.), it is better to configure single email addresses that will be the only endpoint for all emails sent to nonexistent mailboxes. That way Odoo ERP can easily process them, and no emails will be lost.

Configuring of a Catchall mailbox user

Sign into https://admin.microsoft.com, go to menu “Users -> Active users” to see list of already created users

If you don’t have the user which will be used like Catchall mailbox, create it by clicking on the button “Add a user”.The name of the user you can write like “ERP Notification” with email info@your-domain.com (recommended alias is ‘catchall’’ but you cat use any one except ‘bounce’, as example we use ‘info’). Note that Role of this user should be “User (no administrator access)” and Product License should have the status Exchange Online or higher.

If you have the user which will be used like Catch All mailbox, you need to make sure that it has required configuration.

First of all you should go to the “Licenses and apps” tab and make sure that the user’s Product License has the status Exchange Online or higher.

After that you should go to the “Mail” tab and make sure that the user has permissions for connections by SMTP, IMAP and POP protocols.

Configuring of a Dynamic Distribution Group

Go to the menu “Admin Center -> Exchange -> Recipients -> Groups”, choose the “Dynamic Distribution list” tab and click “Add a group”.

Choose the “Dynamic distribution” point and click “Next”.

Now enter the following values in the fields and click “Next”:
- Name = “Dynamic All Users” (you can use any you want)
- Description = “Dynamic All Users” (you can use any you want)

Choose the following values in the fields and click “Next”:
- Members = “Users with Exchange mailboxes” and “Mail-enabled groups”

Enter the following values in the fields and click “Next”:
- Alias = “alldynamicusers” (you can use any you want)
- Domain = the same domain like for Catchall mailbox

Confirm the group creation by clicking “Create group”

As result you can see the same as at examples below:

Configuring of a Mail Flow Rule

Go to the menu “Admin Center -> Exchange -> Mail flow -> Rules”. In this section we are going to create a special mail flow rule that will allow you to catch all emails to unknown email addresses and will forward them to info@your-domain.com, so Odoo ERP can process and analyze them. Click the “Add a rule” and choose the “Create a new rule”.

In opened form enter the following values in the fields and click “Next”:
- Name = “Catchall for Odoo”
- Apply this rule if = “Apply to all messages”
- Do the following = Redirect the message to your Catchall user (here you can select email address created in earlier stages)
- Except if = The recipient is located “NotInOrganization” OR The recipient is a Member of All Dynamic Users group (those rules are needed not to do anything with messages that are sent to external email addresses or that are sent to real users in your organization)

Then enter the following values in the fields and click “Next”:
- Rule mode = “Enforce”
- Severity = “High” (if any issues we want to debug this)
- Stop Processing more rules = Selected

As a result, after saving your rule it will look like the screens below.

Configuring of a Internal Relay for Accepted Domain

Note that after executing the above, the process is not finished yet. Now if you try to send email to non-existent email addresses, Microsoft will bounce back this email to the user saying that “Such email address does not exist”. We need to switch off this feature of Microsoft on our domain (but later we will need to replicate it on Odoo side, but that is next steps). For now, we should go to the menu “Admin Center -> Exchange -> Mail flow -> Accepted domains” and find our domain

Now edit your domain and set its type to be an “Internal Relay” as shown on the image below

Configuring of a Azure App for connection to Catchall mailbox

To have the possibility to connect to the Catchall mailbox from Odoo it is needed to create an entrypoint with special permissions. To do this we should go to the menu “Admin Center -> Azure Active Directory admin center -> Azure Active Directory -> App registration” and click “New registration”.

Enter the following values in the fields and click “Register”:
- Name = “OdooMail” (you can use any you want)
- Supported account types = “Accounts in any organization directory and personal Microsoft accounts”
- Redirect URI = “Web” and “https://your-domain.com/microsoft_outlook/confirm” (domain of your odoo instance, it can be not same as mail domain)

In the result we see a new app. Be sure to copy and save the “Application (client) ID”, it will be required in configuring of a connection to Catchall mailbox from Odoo.

Then we should give the app special permissions. For this go to the “App permissions” and click “Add a permission”.

In the form go to the “Microsoft APIs” tab and click “Microsoft Graph”.

After that choose “Delegated permissions”, find and check “SMTP.Send”, “IMAP.AccessAsUser.All”, “IMAP.AccessAsUser.All” and then click “Add permissions”.

As a result we will see the same as in the example below.

Now we should create the app secret key. For this go to “Certificates & secrets”, choose the “Client secrets” tab and click “New client secrets”.

Enter the following values in the fields and click “Add”:
- Description = “OdooMail” (you can use any you want)
- Expiries = Choose any secret expires you want

As a result we will see the same as in the example below. Be sure to copy and save the “Value” of the created “Client secret”, it will be required in configuring of a connection to Catchall mailbox from Odoo.

Note. If the domain of your odoo instance was changed you should update “Redirect URL” as shown below.

Installing Odoo module to inform users that they used the wrong email

In the previous steps, we have configured Office 365 so it will accept all emails sent to a specific domain, even if those email addresses don’t exist. This means users will not even know that they made a mistake and used the wrong email address. For that purpose you need to perform the following steps:

You need to install this module https://www.odoo.com/apps/modules/15.0/fetchmail_notify_error_to_sender/ At the moment of writing this module is available only for Odoo 9-15. If you need this module with other versions, please let us know.
After installing this module, when some user is sending an email to some mail address that does not exist in Office 365 and does not exist in Odoo ERP (no objects are associated with it), then he will receive the message below automatically.

Configuring Outgoing Mail Server in Odoo

Outgoing mail server is needed to allow Odoo to send messages and notifications to mailboxes of recipients that are inside and outside Odoo. Below are the steps needed to make this configuration and health check.

Configuring of Odoo Outgoing connection

Login as Administrator in Odoo ERP, enter the Debug mode and go to “Settings -> Technical -> Outgoing Mail Servers”. Either select an existing one (to modify it) or click “Create” to create a new one.

Then you need to enter the following values, click at “Test Connection” and save settings:
- Description = “Office 365”
- SMTP Server = MX value from DNS records of your mail domain (see here)
- Port = “25”
- Connection Security = “TLS (STARTSSL)”
- From Filter = “@your-domain.com” – it is needed to send messages with sender which has any alias and your mail domain but in case other domain will be used default sender alias (work since Odoo v15)

To use analog “From Filter” field in Odoo below v15 you should use the key mail.dynamic.smtp.from and set the value as the email address that should be used in those cases as shown below, for example such as outgoing@your-domain.com (documentation).

Testing of Outgoing Mail Server in Odoo

Go to your user settings and set “Email” which will contain your mail domain. You can see example below:

After that, go to any unnecessary contact, set “Email” on which you can receive a message. Then click “Send message”, fill in any text message and click “Send” (before sending make sure that contact is a follower of the current chat).

Then go to the recipient mailbox and check inbox messages. One of them has to be received from Odoo ERR like at example below.

Configuring Incoming Mail Server in Odoo

Incoming mail server is needed to allow Odoo to scan some particular mailboxes for new emails. And depending on the “To” address, it can create new objects like Leads, Tasks and more (or add messages to existing objects). Below are the steps needed to make this configuration and health check.

Configuring of Odoo Incoming connection

Then go to “Settings -> General Settings -> Discuss”, enter the following values and click “Save”:
- External Email Servers = Selected
- Domain = the same domain like for Catchall mailbox
- Client ID = Client ID from your Azure App (see here)
- Client Secret = Secret Value from Azure App (see here)

If your Odoo version is v17 you should add Alias Domain in the next way:

Name – this parameter should have your-domain.com
Catchall Alias – enter here part of the email previously configured. For example “info” in case you have previously configured the email info@your-domain.com

After that go to “Settings -> Technical -> Incoming Mail Servers”. Either select an existing one (to modify it) or click “Create” to create a new one.

Now enter the following values and click “Connect your Outlook account”:
- Name = “Office 365”
- Server Type = “IMAP”
- Outlook = Selected
- Username = info@your-domain.com (Catchall mailbox)

Then “Login” by your Catchall mailbox user.

As a result you will see that Odoo ERP got a Valid Outlook Token. So next click “Test & Confirm”.

As you can see, the connection to the Catchall mailbox was successful.

Check that on “Advanced” Tab you have set field “Error notice template” to the value “Fetchmail – error notice”. Or in other case, when user will send email to nonexistent mailbox that cannot be processed by Odoo – he will not get error message about it.
Then go to the menu “Settings -> Technical -> System Parameters”. And make sure that the properties below are set up correctly:
1. web.base.url – should be equal to the URL of your Odoo instance. It is needed in order to include a proper URL in all your emails
2. web.base.url.freeze – we recommend to add this parameter also with the value “True”. Odoo ERP’s default behavior on login of administrative user is to replace web.base.url parameter with the current url used by the admin. In most cases it is not desired behavior and we want to preserve the URL we have added
3. These settings should be checked if Odoo version is less than v17:
4. mail.catchall.domain – this parameter should have your-domain.com
5. mail.catchall.alias – enter here part of the email previously configured. For example “info” in case you have previously configured the email info@your-domain.com

Testing of Incoming Mail Server in Odoo

As Administrator or any powerful user go to menu “CRM -> Sales -> Teams” and open any team’s configuration. On the sales team details, enter the following data:
- Email Alias = “sales” (you can enter any)
- Accept Emails From = “Everyone”
- Team Members – add some real users with real email addresses
- Followers (in the chatter, optional) – add users that should automatically receive mail notifications when a new lead is coming.

Now send something from your personal email address to the mail address specified in Sales Team. Wait for at least 5 minutes. That is the period that Odoo is configured by standard to download incoming mails.
Now go to menu “CRM -> Pipeline” and You will see that a new Opportunity was automatically created from the incoming email with the name which is the same with email subject. If you already configured Outgoing Mail Server you can start conversation by chatter from this Opportunity.

Bingo! You are done with your configuration of Office 365 and Odoo ERP.

Thanks for the good article.
"And obviously when you respond to the person through Odoo CRM, your lead will also see that email is coming from realperson@company.com instead of some generic email erp@company.com."
In my opinion this is complete malarkey. So, a state official sends an email to our Odoo with something like bob@mi6.gov, and Odoo S.A. thinks it's okay that we will relay it using our own Office account?? There's a very good reason why we have such technologies as SPF, DKIM and DMARC; prevention of spam and fraud, and other unauthorized email. If you go through your own email, you will notice that services such as
- GitLab
- GitHub
- Zendesk
- Google Issue Tracker
and a number of other services _DO NOT CLAIM TO BE THE ORIGINAL SENDER_ in the emails they send. For instance, GitHub conversations will be sent from the address "GitHub Username ".
We stopped using Office365 emails for our clients because a few clients had a high spam rate in outgoing mails sent by Odoo, even though all the settings and DNS configurations were properly set.
Our default configuration contains a module that can be used to set a static Sender address, static From address, static Reply-To address and now even create an alias for every thread. The latter feature was developed because some email clients (read: some versions of Outlook for Windows) don't preserve the headers that Odoo includes in the emails. But luckily even those email clients respect the Reply-To address, so we can add the custom autogenerated email alias to every message. We will most likely contribute this module to some OCA repository.
So, whenever we send email from Odoo with that module installed and properly configured, the headers will be:
From: Original Sender
Reply-To: Original Sender

  Hi Mikko,
  As a technical person I absolutely agree with everything you are saying. Many years ago I was studying how emails are working and was VERY surprised after I saw code on how Odoo works. I was very curious - why we are still not in SPAM. I was hating an idea that company mail server will be acting as a relay server sending emails from unknown mails. I was very worried at this moment about this topic and even used to install special modules for Odoo to stop using Odoo as relay server
  Here is this module
  It is very easy fix that replaces FROM header in all outgoing mails always to be equal to SMTP username of the outgoing mail server.
  Here is code that is added to standard Odoo
  I guess some similar fixes you have in your internal setup. Moreover, internally obviously I tried many other ways including dedicated mail addresses for various mail threads and etc. (like you mentioned)
  I started digging deeper and found out that it is POSSIBLE setup. And even such providers as Office 365 and Google Apps allows this setup. One limitations I know is that Google is not allowing to relay addresses with "@*.ru". Also hotmail has more strict SPF policy and sometimes mails are not passing.
  Moreover, other transactional services like MailGun can be used for this to avoid using your own mail server for this purpose. Moreover, I recommend to use them rather than your own Google Apps or Office 365. Just to be 100% on safe side.
  Also just to finish this technical discussion, as far as I know from here SPF FAQ , SPF protection was designed only to verify the Return-Path/Sender/Bounce/Envelope-from of an email (at the SMTP transaction level), and not "From" header of an email.
  That is why still this setup (as relay server) is working fine even in current modern world.
  So from TECHNICAL point of view I agree with you that this article is not 100% reliable solution, cause it more relies on standard Odoo mechanism that is not perfect.
  Moreover, as you indicated - some mail clients (again Microsoft =) ) do not appropriately handle mails from Odoo when we reply to them.
  An easy fix for Odoo will be that emails will be from single email address (so will be like FROM: "Oleg Kuryan via Odoo ". That can be done with module I mentioned above.
  But let's now look at this solution from END USER point of view. Such setup really irritates business users. For example, because gmail is saving address "erp@yourdomain.com" under some name like "Your Company" in your address book, it will display all your mails as from "Your Company" and not from individual users (Gmail Web interface just ignores From header and displays mail like it is in address book). And that really irritates sales people who stop understanding who they get mails from. I got such situation in my company before, so I know what I'm talking about. =)
  Even better solution will be github like solution. Means every partner in Odoo will get his own alias (like okuryan-alias-odoo@yourdomain.com). And such aliases will be generated for every partners in unique way. If Odoo will support such setup - that will be much better. AFAIK, there is no such solution in Odoo world yet. We were not planning to work on such solution, but if you are ok with it - we can collaborate on this to provide to the Odoo world such a solution.
  By the way - mailing setup is VERY interesting topic. It is even actively discussed by Odoo themselves. Many mail threads, but here is latest https://github.com/odoo/odoo/pull/20911
  Note, that this article was created to provide instructions on setting up email + Odoo in a way Odoo S.A. designed it by standard.
  Will be happy to communicate about it further as this is very interesting topic to me.

Thanks for the good article.
Today we implemented all the steps to configure the "Relay Server", with some exceptions:
(1) The "erp@mydomain.com" account is assigned with an "Office 365 Business Essential" license instead of "Business Premium". It seemed Business Essential license is the minimum subscription level which IMAP access is granted. Not sure nor tested if POP will work in this case.
(2) We have 3 domains configured at the same Office365 tenant, e.g.
-- Tenant-X.onmicrosoft.com
-- Company-X.com (This is the "default domain")
-- Company-Y.com
We configured the "ERP account", the "CatchAll Rule" and "Internal Relay " ...etc., all with the domain name "Company-Y.com".
At the step setting the domain type to be an “Internal Relay”, the "Make this the default domain" checkbox is grey-out (because Company-X.com is the default domain).
We did NOT install the "Odoo module to inform users that they used the wrong email".
The result is -- it does CatchAll, but seems not Relaying -- all the incoming and outgoing emails from both domains Company-X.com and Company-Y.com are caught to "erp@Company-Y.com", but not further relayed to the email's recipients. The same occurs to the emails from third-party email providers such as "personal-email@outlook.com".

  Hello Jade,
  Most likely here is the question how you configured Exceptions. I mean:
  d. Except if = The recipient is located Outside the organization OR The recipient is a Member of All Users group (those rules are needed not to do anything with messages that are sent to external email addresses or that are sent to real users in your organization)

What else can I check?

  First thing you need to check if connection to your host:port is allowed via TLS from your VM.

Hello,
I did exactly what the Tutorial said, but in the end, i got this message from Odoo server error:
--------------------------
The server refused the sender address (******@******.com) with error b'5.5.2 Send hello first [DB5EUR03FT008.eop-EUR03.prod.protection.outlook.com]'
----------------------------
When i debugged in odoo python code, i found that the catched smtp error code is 503
I searched for what it means, they said that the two most common causes of this error are:
-Your email server requires you to check email first before sending email. (Checking email first is one way -your email provider manages the security of your email account.)
-Your email client isn’t set up for SMTP Authentication.
Can you help me please, i couldn't figure it out.

  Hi there,
  I am having the same problem. It seems to be an issue with the way Odoo communicates with the mail server.
  By searching with the error, I found out that error iusually occurs when the HELO or EHLO message is not send at the right time or when the other one is needed.
  Does somebody know a way to fix this?

Hi - thanks for the article. I followed the instructions in your article for the Outbound e-mail, on Odoo Community edition V13.0. However, when I try to test the connection (with SMTP Server set to the MXTOOLBOX outlook.com record) I get this error: "Connection Test Failed! Here is what we got instead: SMTP AUTH extension not supported by server." Sending an invitation e-mail gets pretty much the asme error... "Something went wrong ! SMTP AUTH extension not supported by server." This is only using port 25. Port 587 fails with a timeout.
If I change the server to smtp.office365.com, using either port 25 or port 587, the test Connection actually succeeds with "Everything seems properly set up!" message. However, when I then try to send a message to a new user, an invitation e-mail, I get the following message:
"Mail delivery failed via SMTP server 'None'.
SMTPDataError: 554
5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. "
Followed by a long string of text which I have truncated, mostly hexadecimal characters.
I have been over the instructions again and again and I can't see how I could have missed anything. So:
a) Does this method still work according to you; and
b) Would you suggest something based on the errors I am receiving please?
Many thanks!

  Hello Martin,
  Yes, article is valid. Just last week I did configuration both for Incoming and Outgoing Mails for one of our customers using this article on v13
  From what I see from error most likely on Outgoing Mail Server (in Odoo) you have added username and password. But you should leave them empty. Because you allowed your Odoo instance to send emails to Office365 without password in earlier steps (when you added IP of your server to Office 365 configuration)

    Thanks Oleg - you are right, I did enter a username and password (your article said it was not necessary but it was there already when I read the article and I thought no harm could come of it.
    I removed them now. When Testing Connection I get a different error now: "Something went wrong ! The server refused the sender address (martin.borg@aviense.eu) with error b'5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [xxxxxxxxxxxxx.eurprd03.prod.outlook.com]'.
    Were the steps above perhaps not enough to allow the sending of anonymous e-mails?

      Martin, this message means that you haven't properly setted up IP address of the server that is allowed to send email. As described in article.
      Or you are trying to setup Office 365 with odoo.sh or Odoo Online due to how Odoo designed them. Note that it is officially not supported, so you can do nothing about it.

    29/08/2020 Reply
    Never mind my previous replies, Oleg.
    I realised that in the course of various tests I had changed the SMTP server back to smtp.office365.com, now I have it back to the MXToolbox obtained xxxxx.outlook.com server, and it works - it works very well indeed, and the e-mails appear to be coming from the e-mail address configured for the company having Odoo.
    I realise now that this is "Direct Send", it does not "Send As" anyone in the Office 365 organisation, and therefore the e-mails sent are not going into the "Sent Items' Folder of any mailbox, which may not always be desirable. Now, this may be overlooked if there was anywhere in Odoo from where I could see all e-mails sent from Odoo, but I am not sure this is the case.
    Also not sure how user will be notified if e-mail is not sent successfully, but I suppose I will have to install "Fetchmail Notify Error to Sender Test" which now exists for V13, and see how that works out.
    Are there not security concerns in having Office 365 open like that, accepting e-mails from literally anyone as long as the message comes from that IP address? Could that not open me up to spoofing, and potentially spamming using my IP address?
    Thanks

Hi Oleg,
Thanks for this well-written article. I followed your instructions and everything seems to be working except sending email from odoo outside my main domain. For instance, my company domain is AAA.com and office350 doesn't have issues delivering emails to AAA.com but it can not send emails to "gmail.com" or any other domain except AAA.com. This is what I'm getting: Unknown error: Mail Delivery Failed Mail delivery failed via SMTP server 'None'. SMTPDataError: ip here Relay Access Denied ATTR36.

Hi there,
Thanks a lot for the excellent tutorial. I followed the tutorial completely, and was able to get the outgoing emails to work (i.e. sending an email from Odoo to myself), but I wasn’t able to get the inbound emails to work.
After I clicked the “Test & Confirm” button for setting up inbound email, it says "User Error - Server replied with the following exception: LOGIN failed". I followed every single step in your tutorial. I even went back to the beginning and verified everything a second time.
I logged in and checked my email for the erp@my-domain.com email address I setup, so the username and password are fine, and multi-factor authentication is disabled for that email address as well. I also sent emails to erp@my-domain.com from both internal and external email addresses, and both worked, so it’s not a problem with the Office 365 account.
I then tried your Odoo v13 add-on, and it didn’t show up in the “advanced” tab, so I assume it just doesn’t work yet for Odoo v14.
Thanks a lot,

  Eventually (but not yet) Microsoft will be disabling basic/legacy authentication, which they said on March 7, 2018 that they would do by October 13, 2020, but it hasn't happened yet...

  Either that or our Office 365 account has basic/legacy authentication disabled in our security defaults.
  https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/concept-fundamentals-security-defaults
  In Thunderbird, to receive emails with erp@my-domain.com, I have to use OAuth2 and I enter my email password in a popup window. Normal authentication with a regular password won't work for Office 365 accounts.

Hello!
Thank you for your amazing tutorial!
Despite being quite technical, you really broke it down to simple steps and I thank you very much for this!
The only small thing that was complicated and out of tutorial was enabling Exchange Online Organization Customization (https://www.enowsoftware.com/solutions-engine/m365-exchange-online-center/enabling-exchange-online-organization-customization). It was necessary for the IP whitelist (Configuring of a Anti-spam thread policy). Everything else was fairly straightforward (I'm still amazed how much work must go into what I consider a standard scenario).
Anyway, you said to let you know if the "Notify Error To Sender" app (https://www.odoo.com/apps/modules/15.0/fetchmail_notify_error_to_sender/) was needed for another version of Odoo ; I installed v16 on premise and unfortunately I'm not able to install this module (it depends on fetchmail that is not here for Odoo 16).
If you need anyone to test or any help with this don't hesitate to let me know
