Appreciate it's an old thread but still Odoo (as of V16) does not officially support Azure AD for OAUTH.
However this very simple open-source module does and works with most versions.
I've used it for many years and been involved in the testing / documentation of it.

Hello

I found this information https://www.odoo.com/documentation/master/applications/general/auth/azure.html, this error is because Odoo does not support connection with oauth microsoft azure.

i've managed to reconfigure and allow to authenticate using Microsoft Graph with the sign in and read profile but now getting:
