I see this sentiment online, but using MS Teams at work, I have a great experience. 2-n way chat threads and video calls, team bulletin boards, and integrated apps like sharepoint, excel, custom internal software, etc.
I use slack, zoom, and discord for a mix of school and personal use, and appreciate what each of these offer, but wouldn’t wish to switch off of Teams for work. I do wish you could message yourself on Teams like slack. That’s a nice quick reference utility.
Why do you offer condolences for MS Teams though?
