Multitasking during a Microsoft Teams meeting
You can continue to use Teams during a meeting. Just select another app outside of the meeting to check on what's going on in other channels or catch up on your messages.
Whenever you navigate away from the meeting screen, it becomes a smaller window at the top of the app. Select that window to return to your meeting in an instant if you need to.
Tap the meeting to see the meeting header where you can return to the team channel or chat, start a chat with participants, or add people from your team to the meeting.
