I presume you are wanting to use mutt with your email. You can try your luck with configuring mutt for O365 using the following: https://staff.washington.edu/shrike/unix/configuring-mutt-neomutt-for-imap-access-to-o365-exchange/ There is substantial evidence online that this method works: however, this needs cooperation of your workplace IT to allow you to add your specific email MUA. Most institutions and MS itself allow it, however I was ultimately not successful in this regard so I was not actually able to try it out. While this would have been easy, I found myself a winding alternative but it all depends on what your institution's parameters are. My wife (and colleague) also looked into writing Graph AI calls about eight years ago and was successful in making the calls but the API itself changed, and this made for a horrible cat-and-mouse operation. In those days, they allowed Graph API app registration at my workplace. But my guess is that if they allow the registration of this app, they will allow registration of the mutt (or whatever) Entra ID app, so you are better off doing this directly. I am not sure if this helps, but before you sink time into this like me, you may want to find out what your parameters and constraints are. If they allow the Entra app registration (for only a specific user), it will perhaps be a 5-10 minute affair that is no less secure, and perhaps even far more than using Outlook 365 on the browser, but you will need a competent and cooperative IT shop.
