Setting up a new workspace or conversation thread for collaboration in Microsoft Teams
I just signed off my account en closed teams, sign in again en it was working again.. You can give that a try?
This didn't work for me sadly, but I'll have some users try and see if it solves their issue. What's interesting is that it seems to affect others differently. I also can't create Teams via the web app (get the same error message), so my only options are through the admin panel or from my phone. Hopefully they get this fixed sooner rather than later, I should be able to create a TEAM within TEAMS.
