There's still some features that haven't been ported over including managing users of a Teams group. You have to go out to the web interface to do that right now. For the normal day-to-day stuff like messaging and meetings it's been better in my experience.
Sysadmins around the world are sitting at their desks and chewing their nails, hoping that the EU goes through and actually makes them stop bundling that garbage with their Office suite so that we can actually look into actually good IM messaging apps instead.
We're a gsuite environment and Google Meet is maybe good we had never tried it because we bought Zoom. My previous job had Teams everywhere and I absolutely hated it.
Ah yes, the last time EU tried to interfere with Microsoft monopoly we got Windows N. Can't wait to see them release Office N after a decade of bureaucracy.
