This is gonna sound like a troll post but i assure you it is not.
I don’t have a coding background but I’ve used Teams in a lot of workplaces and really only encountered like 2 issues entirely.
Either I got seriously lucky or it was before enshittification.
Why do you yourself dislike it? Is it UI? Performance?
I should also say I use Teams for basic purposes like messaging and uploading files, I literally don’t touch anything else and performance hadn’t been an issue. (Likely because I’ve been given thicc-ass workstations in the past)
Teams for chat and video is generally OK but when managers start trying to do scheduling, task lists, and kanbans in it it becomes annoying in my experience. A software should have a definitive scope and not try to be an everything tool. If you want that interconnectivity then it’s better to implement a standard which works with another tool that is designed for that purpose instead of tacking on a bunch of shit.
Otherwise, I end up wondering “Ok where the fuck is that scheduled meeting? Was in in outlook? Was it in the teams calendar? Was it in the teams Kanban? Was it a task list item in Teams? Was it in slack? Was it in google calendar? Oh, no, it was in ZOOM! Oh wait, fuck, I actually have a meeting with this client through SKYPE FOR BUSINESS at the same time the zoom meeting starts… Shit.”
