Outlook Disconnected MFA causing issue

I’m hoping this is the final note on this chapter for me as well.  Ran through all the suggestions and, unfortunately, no go for me.  However, instead of the “Fix accounts” I removed/disconnected the users “Work or school account” and this is where it became an issue.  So far the 2 that I’ve tested have not removed one took a log off/on and the other needed rebooted entirely.  After the account is removed I restarted and then when everything came up asking to sign in i close them all out and opened outlook first.  When asked to allow this app to sign me into other apps I selected “No, sign into this app only” after I did that outlook attempted to connect and was presented with a certificate error for outlook.office365.com it said the certificate was revoked but saying no to it outlook wouldn’t allow outlook to connect, but saying yes to it allowed outlook to connect I looked at the certificate and it all looks legit so I’m wondering if something that someone setup before I started here is doing something to the connection.  So far have tested on 2 users and one has ran more than 2 days without issue and other has as well, but they’re not saying it’s fixed until Wednesday.  So far that’s the news!  Hopefully this thread helps someone if they run into this disaster.
