Hi folks, is this still happening for you? If so, please send me your logs at sparavi (at) Microsoft (dot) com. I’ll see if we can repro the issue and figure out what’s going on.

Same here. 'Add Team' does nothing. The dependencies on Azure 'self-service group creation' permissions and perms for creating Office 365 Groups are not well documented. It's not clear what controls on Office 365 Groups are allowed (such as limits on 'who' can create them). I suspect that any controls on Office 365 Groups creation are incompatible with the 'Add Team' functionality in Microsoft Teams. I have opened a support request with Microsoft to address this, and I'll report back what I hear.
