I don't think Exchange online support anything other than OAuth2.0 now (https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online). I use mutt at office with O365. I used plain auth in the past but had to switch to OAuth2.0 this year. I used this blog post to configure mine to use OAuth2.0: (https://www.vanormondt.net/~peter/blog/2021-03-16-mutt-office365-mfa.html). However, I continued to run into problems regulary because of quirks of Exchange server. Now I use mutt with O365 with davmail. It works reliably but feels a lot slower. -- Regards, Sadeep PGP: 103BF9E3E750BF7E
