My university uses MS for their services, and they stubbornly refuse to let me use IMAP (not even with OAuth). I have to either use GNOME Evolution for Micro$oft exchange protocol or a proprietary app on my phone, which enforces bullshit control on a device I paid for.

That's basically the raison d'etre. You, presumably a student, are getting caught in the crossfire of regulatory compliance and they don't want to maintain two email systems.
