The Gmail token script (the one included with mutt) hardcodes the token endpoints and scope names used by Gmail, so one must change those to the corresponding Microsoft values, documented here: https://docs.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth The biggest hurdle is the bit on "Register an Application". When you go to portal.azure.com and select Azure Active Directory / Manage / App registrations, if you are denied access then you'll have to seek permission/assistance from your Azure admin. Alex
