I have an office account for work. I don’t happen upon the troubles people report here. I couldn’t leave MS as I basically use all their stuff for work (and so do the several other hundreds of employees here). But teams does work well: texting, videocalls with 100s of participants, recording meetings, file repositories
I use teams every day. My only gripe recently is the messages like “look the wonderful things we did to improve it” that I didn’t need and will probably never use, but I press the little X don’t know don’t care
