Managing presence indicators such as Available, Busy, or Away to reflect user availability
Hi Dylan and All,
I had the same issue this morning when my teams app updated to the NEW platform. After several trial and errors, I was able to get the # of messages on my taskbar icon!
You will need to uninstall the old teams app (classic version) and make sure you also have "Register the new Teams as the chat app for Microsoft 365 (requires restarting Microsoft 365 applications)" as Brooke mentioned! This also fixed my issue of not seeing statuses within outlook when responding to emails.
I still cannot update my status from taskbar icon and the NEW label is there, but I can now at least see the number of messages I have to respond too. I hope this helps!
