Hello Phil
Yes, you can use the 85t with teams etc. without any problems. Ideally, you should use the Jabra USB dongle. This gives you even more settings to choose from than if you connect the headphones directly to Bluetooth. I usually connect to the PC (via the dongle) and the mobile phone at the same time and set it in the settings so that when a call is made, the other connection is automatically disconnected as long as the call is active.
