Whiteboard offers different features based on whether or not your Microsoft Teams Room (MTR) is connected to a touchscreen.
Using whiteboard on a touchscreen device
With a touch display connected to your Teams Rooms device, a whiteboard shared in a meeting is fully interactive on the touch screen. To learn more, see Whiteboard features and functionality.
Using whiteboard on a non-touchscreen device
If your MTR device is connected to a standard screen or projector, you will be able to view but not interact with a whiteboard.
