Hi All,

Just to share after following the documentation to connect to Microsoft 365, I was getting errors when attempting to test the connection. https://www.odoo.com/documentation/18.0/applications/general/email_communication/azure_oauth.html

I worked out that SMTP Auth is generally disabled by default in the Microsoft 365 Tenant. You either need to enable it tenant wide, or on a per-user basis (preferred option).

There are various ways to enable this (via the GUI or script).

Below is via the GUI per user:

1. In Microsoft Admin Center
2. Go to Users > Active Users > Select the applicable user
3. In the Window on the right > Choose Mail > Manage email Apps
4. Ensure "Authenticated SMTP" is selected.
5. Test!

Hope this saves someone unnecessary hair pulling! (and maybe it could be added to the documentation)

EDIT: I've got screenshots but as a fresh user, I'm not allowed to post the images. Sorry.
