Due to org policy, you can’t use (hotmail) with Teams on this device.

This is my personal desktop and I'm using my personal email. How do I remove this from an organization?

@AlexPuhl Hi, with the brief info here I'm only guessing this is because of a device policy preventing sign in with a personal account.

'How to restrict sign in on desktop devices'

Sign in to Microsoft Teams - Microsoft Teams | Microsoft Docs

@ChristianBergstrom Thanks for the assistance, I couldn't find any of the regedit's mentioned in that article.

Decided to try and completely uninstall MS Teams, after that I found that it was still on my system for some reason, but decided to boot it up and give it another try and it's working all the sudden. No clue what that's all about.
