I'm trying to install Teams on my Apple MAC. I've downloaded the software and just as the installation completes, Teams starts up, but shows the error message below.
I have a licence for a Small Business O365 (persistent licence rather than subscription). Teams isn't included with the licence, but I don't know if this is the issue. Either way, I'm stuck here as I can't get passed this window. If I click on the "sign out" link, it just fires up the same window with the same error.
