Unable to issue tokens from this API version (AADSTS500201)

[SimPilotAdamT]

Originally from #180, but that has been inactive since it was opened in 2021.

When using M365Interactive and M365Manual, the login prompt fails, showing the following error message:

AADSTS500201: We are unable to issue tokens from this 
API version for a Microsoft account. Please contact the 
application vendor as they need to use version 2.0 of the
protocol to support this.

According to this SO answer mentioned in #180 (comment), Davmail needs to change over to using ADFS for new logins to be successful. #134 fixes this issue iirc...

I'm facing the same issue, and therefore cannot access anymore my Outlook account with davmail (since October 1st, when Microsoft started enforcing the new authentication method). Is there a workaround?

I ended up ditching Davmail in favor of mutt_oauth2.py (along with mpop and msmtp). I had to join Microsoft Azure free account and configure it to allow accesses from mutt_oauth2.py, but it is working fine now.
