Setting aside the issue of whether this post is overstating the risk of MDM software on a personal phone, I had a tangentially related experience that might provide a tip for anyone who's in a similar situation.

I like to have the convenience of checking my work messages and chats on my personal phone, so I have Teams and Outlook installed and using my work account.

When I first went to sign in to my work account on Outlook, I got this message like "Outlook needs to run with administrator privileges in order to provide the necessary security for this account" and shunted me off to some system settings to approve the permissions. Big nope.

So I tried Outlook Lite, and it made no such demands and works perfectly. So for anyone else who's run into this, try Outlook Lite! I hope this helps somebody.
