A whole new toolbar appeared in Outlook on my work computer with nothing but a single button to open a copilot chat window. I tried asking it a few simple questions and it completely failed at all of them. Copilot didn't even know if I was using the web or desktop version of the very app it was embedded in!

Wasting UI space for a useless tool it's just a waste of time, it actively makes it harder to get work done. But I guess the important thing is the number of times that AI button gets clicked is going up on some PMs telemetry dashboard.
