MicrosoftjschinaSo you have the unit in Skype only mode and the unit is not setup with Teams in the O365 tenant?
I think we would need to do a few things to get to the bottom of the issue:
1. Collect the version information of the unit. (This could be a version issue so we'd need to document for MS exactly what you are using)
2. Reproduce at Crestron which shouldn't be hard if this is all the public versions and its as easy as this.
3. Get a case opened with Crestron support. (1-888-CRESTRON) or support@crestron.com can be used and they can start a case.
4. Support can help troubleshoot sign in issues and if they can be replicated, then they can be escalated to the appropriate Microsoft department and ultimately even to Ilya's group if need be.
I don't have access to a unit right now, but I have seen Skype only installs work flawlessly and not give this error so my thought process is it could be your auto discovery or something in your environments DNS that might be causing the issue unless its a very old version of the software.
