You can also share a PowerPoint presentation in a meeting and control that presentation from right within the Teams meeting window.
Click the Share Screen button on the meeting controls bar.
In addition to the desktop and open windows, the screen sharing pane will display some recent PowerPoint presentations you've opened on your team's SharePoint site or your OneDrive. If the presentation you want to share appears here, just click it.
You can browse for a presentation in a team channel's file library, select one from your OneDrive, or upload a presentation from your computer.
Select a location.
Select a presentation.
The presentation is uploaded to the file library of the meeting's team channel, or to your OneDrive if the meeting isn't taking place in a team channel.
Once the presentation is uploaded, it starts on the first slide. A small controls bar appears, showing your progress and letting you navigate through the presentation.
Use the left and right arrows to navigate the presentation.
As you move through the presentation, everyone else in the meeting will automatically move through it with you.
Click the eye icon to toggle private viewing.
While private viewing is enabled, meeting participants will be able to move through the presentation on their own. If private viewing is disabled, everyone will be restricted to viewing the slide that you’re on.
Click Stop presenting.
The presentation closes, and the Teams meeting window returns to normal.
