So it's a neat feature.
But, it doesn't work in the Outlook Android App, which kinda makes Workspace Mailboxes pointless.
And, it took about ~3 Days till the Room Finder was populated with the right parameters.
Now I can't change them anymore on our Room Mboxes (Hybrid), since Set-Place -identity "Email address removed" -VideoDeviceName "Device" throws an internal server error.
I can't set any attribute on our synced mboxes anymore, I tried VideoDeviceName, AudioDeviceName, DisplayDeviceName, Tags - everything separate and everything throws an internal server error in my EXO Powershell and there is obviously no way to set it onprem.
Currently it's completely broken for us.
