Fix PowerPoint Will Not Open in Desktop App from Teams or SharePoint
Question details
Users are unable to launch PowerPoint presentations in the desktop application when selecting the 'Open in desktop app' option from Microsoft Teams or SharePoint, even after running a standard Office repair.
- Product
- Microsoft PowerPoint, Microsoft Teams, SharePoint
- Device & OS
- Windows
- Scenario
- Attempting to open a hosted presentation locally using the 'Open in desktop app' feature from Teams or SharePoint online.
- Observed behavior
- The PowerPoint desktop application fails to launch or open the selected file, trapping the user in the web viewer or Teams interface.
Ensure that your local Microsoft Office suite is activated and that you are signed into the desktop application with the same account used for Microsoft Teams and SharePoint.
Test Opening Directly from the SharePoint Library
Isolate the issue by testing if the failure is specific to the Teams application or if it affects the entire SharePoint integration.
Open your web browser and navigate directly to the SharePoint document library where the PowerPoint file is hosted.
Locate the file, click the three-dot menu (More actions) next to it, and select 'Open in Desktop App'.
Repeat this process with several different files to determine whether the problem affects just one corrupted document or the entire PowerPoint application.
Completely Uninstall and Reinstall Office
If a standard Control Panel repair fails to fix the integration, use Microsoft's specialized uninstall tool to perform a clean installation.
Diagnose with a Temporary Windows User Profile
Create a new, temporary Windows profile to test if the issue is being caused by corrupted data in your current local user account.
Switch to WPS Office for a Hassle-Free Experience
If Microsoft Office integrations continue to fail or require complex troubleshooting, consider WPS Office as a lightweight, highly compatible alternative. It opens and edits standard presentation formats without complex account syncing issues.
Frequently Asked Questions
Can I just use the standard Office repair in the Control Panel to fix this?
In many cases, the standard 'Quick Repair' or 'Online Repair' from the Windows Control Panel does not resolve deep protocol integration issues between Teams and the desktop app. Using the complete uninstall support tool is highly recommended.
What should I do if the file opens in Teams online but not in the desktop app?
If the presentation opens properly in Teams online or Office for the Web, the document itself is uncorrupted. The issue is strictly related to a broken communication link in your local Office installation, which usually requires a clean reinstall of the desktop software.
Will I lose my files if I use the Office uninstall support tool?
No, uninstalling Microsoft Office only removes the application software. Your personal documents, presentations, and files saved locally, on SharePoint, or in OneDrive will remain completely safe and untouched.
