Fix PowerPoint Not Opening Local Files While Teams Presentation is Open
Question details
Users are unable to open local or emailed PowerPoint presentations by double-clicking them when another presentation, launched from Microsoft Teams, is already open in the desktop app.
- Product
- Microsoft PowerPoint, Microsoft Teams
- Device & OS
- Windows
- Scenario
- Trying to open a local PowerPoint file for reference or asset copying while actively collaborating on a shared presentation that was opened via the "Open in App" button in Microsoft Teams.
- Observed behavior
- Double-clicking a local .pptx file results in no action. The file fails to open entirely until the shared Teams presentation is closed, after which the local files open normally.
Ensure you save any recent edits in your shared Teams presentation, as troubleshooting this integration issue may require restarting both Microsoft Teams and PowerPoint.
Sync the Teams Document Library via OneDrive Client
Opening the shared file from a synced local folder bypasses the Teams direct-launch integration bug that blocks other PowerPoint files from opening.
When you use the "Open in App" feature directly from Teams, temporary file lock conflicts can occur within the Office application. Using the OneDrive sync client to access the shared folder locally prevents these conflicts.
Open Microsoft Teams, go to your project channel, and click on the 'Files' tab at the top where the shared presentation is stored.
Click the 'Sync' button in the toolbar. This will prompt the OneDrive client to map the Teams document library to your local computer.
Open Windows File Explorer, navigate to the newly created company synced folder (usually under your organization's name), and double-click the shared presentation to open it.
With the shared file open, try double-clicking your local .pptx files on your desktop to verify they now open simultaneously.
Open Local Files Directly from Within PowerPoint
Bypassing the double-click action in Windows File Explorer can force the local file to open inside the active PowerPoint session.
Update Microsoft 365 Apps
Installing the latest updates can resolve known PowerPoint and Teams integration glitches that cause file locking issues.
Try WPS Office to Seamlessly Open Multiple Presentations
If Microsoft PowerPoint continues to freeze or block local files when collaborating via Teams, WPS Office provides a stable, lightweight, and completely free alternative. You can use it to open your local presentations without conflicting with Microsoft Office's background processes.
- 1. Download the installer: Visit the official WPS Office website and download the free installation package.
- 2. Install the software: Run the installer and follow the on-screen instructions to set up WPS Office on your Windows PC.
- 3. Open your local files: Right-click your local .pptx file, select 'Open with', and choose WPS Presentation to easily view your local deck without disrupting your Teams session.
Frequently Asked Questions
Why does this issue only happen with PowerPoint and not Word or Excel?
This issue is tied to how the PowerPoint desktop app handles specific temporary files and application state flags when linked to Microsoft Teams. Word and Excel manage concurrent file locking differently, which is why they generally do not exhibit this bug.
Will reinstalling Microsoft Teams fix the PowerPoint issue?
Reinstalling Teams might help if the local cache is corrupted. However, mapping the document library via the OneDrive sync client or updating your Microsoft 365 apps is typically a much more reliable and permanent solution.
Can I edit the Teams file without opening the desktop app to avoid this?
Yes. If you choose 'Edit in Teams' or 'Open in Browser' (PowerPoint for the Web) instead of 'Open in Desktop App', your local PowerPoint desktop application will remain completely free to open local files without any conflicts.
