Microsoft has a solution to that problem: Teams. It is so painful to use and to do anything in it that it encourages people to actually use the bug tracker or other venues to discuss any serious topic.
But I guess it allows management to spy on employees while being integrated with the microsoft ecosystem, so it gets a free pass.
I figured I could get used to teams, but it’s just so useless compared to Slack it isn’t even funny.
This was actually fixed a ~month ago. And they broke the ability to answer group call in the mobile app with that update.
