Content sharing settings control how users present a screen or app during a chat, meeting, webinar, or town hall. You can configure admin settings for screen sharing mode, PowerPoint sharing, whiteboard, and shared notes. (For information about how to manage who can present and who can request control, see Manage who can present and request control in Teams meetings.)
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.
The Whiteboard setting for Teams meetings is a per-user setting. This setting controls whether a user can share the whiteboard in a meeting. External participants, including anonymous, guest, and external access users, inherit the policy of the meeting organizer.
When whiteboard is enabled, users can use annotations, a feature that allows participants to collaborate while sharing their screen in a Teams meeting. If Whiteboard isn't enabled, users don't have access to annotations.
In Microsoft Teams: While in a Teams meeting, you can share a whiteboard from the Share tray, or you can also prepare your board ahead of time and then present it. In a Teams channel or chat, you can add a whiteboard by selecting the + button at the top of the screen, and then searching for Whiteboard. For more information, see How to use Whiteboard in Microsoft Teams.
Microsoft Whiteboard is a collaboration tool that allows Microsoft users to quickly share ideas with other people. The app allows you and your team to draw or write as if you are using ink. Although designed to work best with a stylus, it's perfectly usable for people with desktop devices. That said, it has good inter-app synergy with other programs in the Microsoft Office suite, so if you're already using Microsoft tools for your team's productivity, then Whiteboard will be a great new addition.
