Because it's objectively worse than every major alternative while being absurdly resource intensive. Just watching it struggle feels like the punchline to a very dry & tragically unfunny joke

Its features are great, like any other web confrence software that does the same.

However the constant UI changes lead to a lot of issues for IT people who have re-tech the entire staff how to use it every update. For a small business thats not probably too bad. For somewhere with hundreds of employee working from home who barley know where the start menu is - that's a nightmare.

The "new" teams doesn't work with business accounts. you have to use the specific, now seperate, version for "work and school". Guess which one the everyone's existing desktop link is to? Now IT has to get everyone to use the right version of teams...an absolutely insane choice and terrible end user expirence.

Teams feels a bit like a never ending beta. On one hand, it's kind of nice to get constant tweaks and it's generally pretty good. On the other, things do break from time to time. There's also the whole "new teams" thing, which feels... very similar to "old teams". All the old sillyness, like not being able to folder dive in a team while chatting (it will forget where you were when you switch back) for not much benefit. It also is a big regression in basics like spell check speed. It takes seconds for a red squiggle to send, so now my spoild self has to wait a bit before hitting enter.

At least it's not new outlook. Everything on that is way slower and it's very clear the UI was not optimized for a computer. Left click to spell check in an email body, right click to spell check in an email title. Want to add formatting in a meeting invite? Ha, that's rich. Even very basic things like changing fonts take forever.

Both feel a bit like a new PM being given the reigns and going at it. I struggle to see what was so wrong with the old versions, especially outlook...
