Whiteboard integration in Microsoft Teams meetings is powered by the Whiteboard web app, which lets Teams meeting participants draw, sketch, and write together on a shared digital canvas. Users can share a whiteboard to make it available to all participants in a Teams meeting. That same whiteboard is simultaneously available in all the Whiteboard applications on Windows 10, iOS, and the web app. To turn the Whiteboard app on or off, see Enable Microsoft Whiteboard for your organization.What is the best Whiteboard app?
