EDIT: Thank you all for detailing your experience with, and hatred for, this miserable product. Your display of solidarity is inspiring. Now, say it with me:
I don't have any strong feelings about Teams. It just is what it is. It's a chat app for work, like it's just there to spy on me and keep me in contact with co-workers. It's whatever. Of all the things I think about in the day, Teams is not one of them.
If it was used strictly as a chat app it still couldn’t hold water to AIM. I’ve got colleagues who insist on storing files there and if you couldn’t imagine SharePoint being any worse try using it in the Teams interface. Microsoft is too big for their own good. Instead of doing 1 thing amazingly, they do 1000 things shittily
