Additional sign-in or account-related issues within Microsoft Teams for business
So with a new Mac there is a glitch and it hands on loading TEAMS.
you can try reinstalling but that doesn't work you need to help it along.
<July 28 : Returning with some more data>
- Open up Calander... go to a TEAMS meeting you have previously scheduled (if you don't have one, log onto the online webs browser version and quickly set one up and email yourself the link)
- Click the Link, it will open up your camera. close that program and then click on TEAM on your MAC
WALA! it somehow fixes the problem!
Enjoy
