Hmm. Wonder if this is the real reason IMAP suddenly stopped working for
me on my work Office365 domain after updating my password. Although it
does work for some people. Weird.

OAuth is the solution for Google, and I suspect OAuth may be the
solution for Microsoft too. If so, you need a program that supports IMAP
using OAuth.

gemail supports Google OAuth, I suspect it might be possible to get it
to work with Microsoft too. However I don't know anything about how to
register the Oauth app with Microsoft.

Apparently OfflineIMAP also supports Oauth.

Another option might be davmail.
