Screen sharing lets you present your screen or the app you're using during a meeting. To share your screen in a meeting, click Share in your meeting controls. You can choose to present your entire desktop, a specific app, or a file.
Share PowerPoint slides in a meeting
If you choose to share a PowerPoint file in a meeting, rather than your desktop, meeting participants will get some special capabilities:
They'll be able to move around to different slides without interrupting the main presentation.
They can sync their view back to the presenter's view with one click.
Click Share in your meeting controls.
In the PowerPoint section, click the file you want. Click Browse to look for a different file.
The PowerPoint section lists the most recent files you've opened or edited in your team SharePoint site or your OneDrive. If you select one of these files to present, all meeting participants will be able to view the slides during the meeting. Their access permissions to the file outside of the meeting won't change.
If you select Browse and choose to present a PowerPoint file that hasn't been uploaded to Teams before, it will get uploaded as part of the meeting. If you're presenting in a channel meeting, the file is uploaded to the Files tab in the channel, where all team members will have access to it. If you're presenting in a private meeting, the file is uploaded to your OneDrive, where only the meeting participants will be able to access it.
Give and take control of a sharing session
If you want another meeting participant to change a file, help you present, or demonstrate something, you can give control to that person. You will both be in control of the sharing, and you can take back control anytime.
Note: When you’re sharing an app, only give control to people you trust. People you give control to may send commands that could affect your system or other apps. We've taken steps to prevent this but haven't tested every possible system customization.
On the sharing toolbar, select Give control.
Select the name of the person you want to give control to.
Teams sends a notification to that person to let them know you’re sharing control. While you’re sharing control, they can make selections, edits, and other modifications to the shared screen.
To take control back, select Take back control.
To take control while another person is sharing, select Request control. Then, the person sharing will approve or deny your request.
While you have control, you can make selections, edits, and other modifications to the shared screen.
When you’re done, select Release control to stop sharing control.
For now, go to the Teams desktop app or Teams on the web to share PowerPoint slides in a Teams meeting. Once you've joined a meeting, you'll be able to view slides and take control of the presentation while using your mobile device.
