This was my experience. Teams was slow and functioning badly this morning, but it wasn't until someone else said they were also not seeing images that I realized it wasn't just typical jank. Teams is just not good to use in the first place so it doesn't occur to me to think I should check for outages whenever I have a problem.

I think especially with how Teams responded to this problem. It wasn't saying it couldn't connect or anything.

I had a few symptoms:

First teams froze my entire computer when I started it when it couldn't connect.

Then it finally loaded and a message I sent would appear in the preview on the left but not actually in the chat window (the preview where it shows the name list of chats I have).

Then messages would just sit with that circle sending, but I would receive messages occasionally.

A simple "can't connect" would have gone a long way.

Today was the first day, in the ~4 months that we've been using Teams and MS365 for our company, that anyone noticed an actual outage. I got an email about it from a colleague and they weren't aware of the outage (I wouldn't expect them to, this team is very non-technical). So I get to explain these types of things next week, that we can't really "fix" these issues, they will happen though.

But yea, Teams is janky. I wish I could say it was the worst thing I experienced at work, but, alas, that remains a wish and a dream.
