I went back again and cleared the contents of the same folder and fired up Teams another time. This time is gave me the option to chose a login, so I chose the same Veeam account… only to have the same issue. I did however have files under Library -> Application Support -> Teams. I cleared the contents of that folder and tried to fire up Teams again. A couple of replies from Microsoft suggested a cleaning out of Cached files under the logged in users Library -> Caches -> folder, but I didn’t have that folder in existence on my system. I came across this Microsoft Support thread that didn’t seem to be that helpful, or offer and specific path to resolution. It would just sit there until it loaded a blank White Window in the background and then do no more. After first apparent successful login, Teams would get stuck on the Loading Microsoft Teams window as shown below.
I was having an issue with Teams after entering my Veeam Work Organisation credentials, and logging in. Teams is a seperate download and install from the core Office 365 Applications which are M1 optimized (Excluding OneDrive). Microsoft Teams is not M1 optimized and runs under rosetta 2. Being new, and on Apple Silicon, I expected a few compatibility issues with some of my older MacOS usuals. I’ve recently gotten my hands on the new Mac Mini M1 which comes with MacOS Big Sur as the default operating system.
