Advanced users of Teams may want to enable apps for their Team.
Apps let outside programs come right into your Team, so that users don't need to visit another app or website to use their functionality. There are lots of apps available - you can browse hundreds by visiting the Teams app page or by clicking the '+' at the top of your team.
Microsoft Whiteboard is a free-form, digital canvas where people, content, and ideas come together. 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.
Whiteboard is available only during a Teams meeting with 3 or more participants.
It is NOT recorded if you record a meeting, but you will be able to access it later via the meeting chat or via the Whiteboard app or webapp.
To open Whiteboard:
Whiteboard is an 'infinite canvas' that lets you scroll in and out, move side to side, and insert text, drawings, images, and post-it notes, and more. Users can collaborate together, editing at the same time.
Teams & Webapp vs the full Whiteboard app
The Teams and webapp versions of Whiteboard are fairly bare-bones - if you plan to use Whiteboard extensively, it is a good idea to download the full app to gain access to many, many more features
