Fix PowerPoint Videos Not Playing Full Screen in Microsoft Teams
Question details
Users are experiencing issues where videos embedded in PowerPoint presentations fail to play in full-screen mode during Microsoft Teams meetings, despite having the setting enabled.
- Product
- Microsoft PowerPoint, Microsoft Teams
- Device & OS
- not provided
- Scenario
- Presenting a PowerPoint slide deck with embedded videos in a Microsoft Teams meeting.
- Observed behavior
- Videos do not play in full-screen mode when shared via Teams, although they function correctly when the presentation is played locally outside of the application.
Ensure that both your Microsoft Teams application and Microsoft PowerPoint software are updated to their latest versions, as this is a known rendering bug.
Contact Microsoft 365 Support for Backend Investigation
Since this is a confirmed reproducible bug with PowerPoint and Teams integration, escalating to Microsoft Support is the official recommendation.
Microsoft community moderators have confirmed that this issue can require backend investigation by their engineering team. Individual end-users cannot fix this through local settings.
If you are not an administrator, ask your IT department or Microsoft 365 Administrator for assistance.
Have the administrator log into the Microsoft 365 Admin Center.
Navigate to the Help & Support section to submit a new service request. Include your exact Teams and PowerPoint versions, presentation details, and the steps to reproduce the problem.
Workaround: Share Screen Instead of PowerPoint Live
Bypass the PowerPoint Live rendering bug by sharing your entire screen or specific window to ensure the video plays correctly.

Frequently Asked Questions
Why do my PowerPoint videos work normally off-call but fail in Microsoft Teams?
When using PowerPoint Live in Teams, the presentation is rendered through a cloud-based backend rather than your local PowerPoint application. This backend process currently has limitations that can prevent full-screen video playback.
Does toggling 'Play Full Screen' in PowerPoint playback settings fix this Teams issue?
Unfortunately, the 'Play Full Screen' playback setting is often ignored by the Teams PowerPoint Live rendering engine, meaning the setting will not resolve the issue when sharing via that method.
How can I ensure attendees hear the audio from my PowerPoint video in Teams?
If you use the screen sharing workaround, you must explicitly check the 'Include computer sound' switch located at the top right of the Teams sharing tray before selecting your screen.
