If you think everything is fine, presumably that's because every metric you have available is indicating fine-ness. That's probably sufficient for most users. There'll be some edge cases, but the brief write-up in some obscure IT online journal should suffice to restore anyone's slightly damaged reputation regarding a torpid non-committal response.
I'd also assume if you're using Microsoft Teams it's because someone else has determined that you shall use it. I expect that any semi-informed, mildly IT literate Microsoft Teams user has a starting position of 'low expectations'.
Anyway, parent was suggesting an in-app message to indicate some issues, so my initial question stands - how do you expediently send an instant message to a user to advise them that your instant messaging app is having a bad day?
