I have one computer with error "user authenticated but not connected". I have already reinstalled software, re-created user account. Changed password.

On account recreation OAuth2 do not display regular app rights display at end of Oauth2 login cycle. Microsoft Mail works on same computer and same account works on other machine.

How to completely reset Thunderbird settings?

Hello

For your information, your post is the third I see today with the same message. In both other cases disabling IPv6 on the computer's network configuration worked around the problem. By the way, OAuth2 is not an absolute requirement to use an Office 365 account. It's still possible to create an app password. So. My advice:

  • remove the problematic account
  • remove IPv6
  • restart your computer - that should take care of any Microsoft shenanigan and restarting Thunderbird too.
  • recreate the account.

If it still makes you grief, try to create an app password in your Office 365 configuration. OAuth2 is overrated, the only real good it does is to separate your account password from the mail password so if the latter is compromised you don't lose access to your account. The app password does the same thing and is much simpler.

Disabling IPv6 solved the issue.
