Teams fails every day at its basic purpose. Chats are confusing, the threaded ones being utterly useless. Constantly have to use the mouse to do basic stuff like address people or change channel. Stuff randomly breaks all the time, syntax highlighting seems to break in some new way every other week. It's complete garbage software and a massive regression for those of us who remember proper, simple chat software from decades ago.
I am not sure if this is a server side thing at Microsoft, or a problem with the application itself. True under Windows, Linux, via local app, and via the web app.
For larger meetings (> 50 people), we use zoom. Unlike teams, zoom generally just works. Quite well in fact.
Teams is simply crap software, forced upon us. If we could jettison that and Outlook, I would be grateful. Though our IT looks at us in an unblinking stare, if we ask them to allow us to use any of the better clients on mobile, laptop, desktop, windows or linux. Its almost as if our third eye in the middle of our forehead opened up.
