OMG. It's an absolute pile of crap on fire. Not just teams - Exchange/Outlook is as bad.

Last year we had Mac users start to report "when I attach a file, it looks like it's sent, but then recipient never sees it, and sent-emails doesn't show it either!" It got worse and worse.

This is kind of a problem in a business that sends and reviews a lot of documents. I spent two months on countless calls with MS, repeatedly capturing videos they requested, etc.

Finally, I happened to come across an advisory that hey, Outlook for Mac is broken, and will "eat" attachments. Dated a week before we started to see the problem. Firstly, it took them MONTHS to get it resolved as it required significant updates to Exchange. Secondly, in all the interactions I had to have with their support team: they had NO IDEA. Worse than useless.
