Davmail seems to work okay for single user systems, but hosting it as a proxy for multiple users seems dicey. I got it running in a container and started down the process of fishing out the OAuth URI from the logs so that I could somehow render it back to the user to complete the authorization process... At that point I started to get skeptical that it would scale and have adequate session isolation. > Thunderbird beta (78.0b2) supports M365’s OAuth2 support natively, no > external shim required. > > The setup is a little weird, you need to set up the account, go to the > advanced settings (so that it creates the account despite not working), > switch the authentication to OAuth2 for both IMAP and SMTP, it just works. Yes, the TB devs did a great job! I assume that Microsoft offered some assistance behind the scenes, so kudos to them too. I'm using it now. I think they're making some improvements to the setup UX based on the comments I've seen in Bugzilla. Once it comes out of beta, I can combine it with the TBSync extension (which syncs the non-email things from M365) it will be my sole MUA again.
