I use my work email address as the username and the work password along
with it when using imap/smtp with davmail.  There are multiple sign-in
options (one of which was selected by your employer) listed at
https://docs.microsoft.com/en-us/azure/active-directory/hybrid/plan-connect-user-signin,
but I think IMAP should work regardless.  My workplace uses federated
authentication, and davmail works fine for me.

Have you tried and failed to authenticate using your email address and
password?
