I would take MSN Messenger 7.5 over teams.
I think most of the problems with it are related to it being pretty much a web app that runs on the desktop. If they had a nice native app that didn’t take 50% cpu to move from chats window to calendar and then made me wait for the calendar to refresh every time, the whole experience would be much nicer.
It tries to do too much and does them all half assed.
Channels and chats being separate when both have chats is just odd to me.
An option to display channel chats in the main chat window would be nice so I don’t have to manually go dig into every channel I’m a part of to see what is being said. I’m sure they have enough brains at MS to come up with a neat way of displaying that.
