Dear Shawn,
It did not work for me in the beginning but it is working fine now. I am using MS Teams on Microsoft Surface daily.
Under Device Settings, I always have to open Blue Tooth Devices and click "connect" for my Airpod Pro. Once it shows "Connected. Music" (and not just "Connected" - it means Teams will pick it up.
Once that step is done, open Teams and under "Device Setting" in Teams, you should see it automatically changed to "Custom Setup" where speakers will be your Airpod and microphone will be your laptop. Cannot have both from Airpod - that does not work somehow.
One other step I did which may be the reason why it now works for me when it did not in the beginning - DO NOT pair Airpod to iPhone. I started out pairing to iPhone first and could not get it to work on MS Teams. Once I unpaired with iPhone, I had no
problems with connecting the Airpods to my Surface and it just works seamlessly on MS Teams.
Hope the above helps!
