Because of COVID19 my workplace has rushed right into Microsoft Teams. There's so much efficiency lost creating large-scale meetings and phone conferences. Coming from the land of IRC I've created a few teams with massive rosters, but nobody seems to really understand the paradigm. They see all these messages come in and they leave the team/discussion/channel.

I keep saying "mute the discussion" and @mentions will signal you if needed, but it is lost on folks who haven't done this kind of things.

They're used to discussion spaces being set up per-incident, instead of just lingering/loitering in a room.
