How to Fix PowerPoint Live Presentation Errors in Microsoft Teams
Question details
The user needs to resolve an error that occurs when attempting to present a slideshow using PowerPoint Live in Microsoft Teams.

- Product
- Microsoft PowerPoint, Microsoft Teams
- Device & OS
- not provided
- Scenario
- Starting a live presentation by selecting the 'Present in Teams' button directly from Microsoft PowerPoint.
- Observed behavior
- Selecting 'Present in Teams' opens Microsoft Teams but produces a generic error message, particularly in the new Teams client, even though the same presentation works in classic Teams.
Ensure both your Microsoft Teams client and Microsoft PowerPoint application are updated to the latest available versions before troubleshooting.
Isolate and Recreate the Problematic Slide
Use a split-testing method to identify the specific slide causing the PowerPoint Live error and replace its unsupported content.
PowerPoint Live relies on the web rendering engine. Sometimes, a specific element, embedded object, or corrupted slide that works fine in the desktop app or classic Teams will cause the new Teams client to fail. Isolating this slide is the most effective way to fix the generic error.
Save two separate copies of your PowerPoint presentation to your local drive or OneDrive.
Open the first copy and delete the second half of the slides. Open the second copy and delete the first half of the slides. Save both files.
Use 'Present in Teams' to test both copies. One of them should produce the error while the other works successfully.
Take the copy that produced the error, split its slides into two new copies, and test again. Repeat this process until you have isolated the single slide causing the issue.
Once identified, delete the problematic slide from your original presentation and recreate its text and media from scratch, avoiding complex animations or unsupported embedded objects.

Verify Presentation in PowerPoint for the Web
Check if the presentation can open properly in the web version of PowerPoint to confirm if the issue is rendering-related.
Temporarily Switch to Classic Microsoft Teams
If you need to present immediately, reverting to classic Teams can temporarily bypass compatibility errors specific to the new Teams client.
Try WPS Office for Seamless and Reliable Presentations
If you frequently encounter compatibility errors or crashes with Microsoft PowerPoint, consider switching to WPS Office. It is a free, lightweight, and highly compatible alternative that makes creating, editing, and sharing slides hassle-free.
- 1. Download and install WPS Office: Visit the official WPS website, download the free installer, and complete the installation on your device.
- 2. Open your presentation: Launch WPS Presentation and open your existing .pptx or .ppt files directly without conversion.
- 3. Share in your meeting: Join your video meeting and use the standard 'Share Screen' or 'Share Window' feature to present your flawless slides to your audience.

Frequently Asked Questions
Why does my presentation work in classic Teams but not the new Teams?
The new Microsoft Teams client uses an updated architecture and stricter compatibility checks for PowerPoint Live. This new framework may reject slides containing complex, legacy, or unsupported elements that classic Teams previously ignored.
What type of content is unsupported in PowerPoint Live?
Content such as complex animations, legacy media formats, macros, and large embedded objects might not be fully supported by PowerPoint for the web, which powers the PowerPoint Live experience in Teams.
How can I present my slides if PowerPoint Live keeps failing?
Instead of using PowerPoint Live, you can use the standard 'Share Screen' or 'Share Window' feature in Microsoft Teams to present your slideshow directly from your desktop presentation application.
