- Product

- Device & OS
- not provided
- Scenario
- Attempting to open and edit a presentation stored in a shared OneDrive directory using the desktop software.

Ensure that your Microsoft account is actively signed into both the OneDrive sync client and the Office desktop applications, and that your internet connection is stable.
Toggle Office File Sync Settings in OneDrive
Refreshing the Office file synchronization setting can resolve application-specific locking conflicts between OneDrive and the PowerPoint desktop app.
OneDrive includes a feature that uses Office applications to sync the Office files you open. Sometimes, this feature causes an Access Denied conflict specific to one app, such as PowerPoint. Disabling and re-enabling this setting forces a refresh of the sync permissions.
Click the OneDrive cloud icon in your Windows taskbar notification area, click the gear icon (Help & Settings), and select 'Settings'.
Navigate to the 'Sync and backup' or 'Office' tab, depending on your version of OneDrive.
Uncheck the option that says 'Use Office applications to sync Office files that I open'. Click OK to save your changes.
Wait a few moments, reopen the OneDrive settings, and re-check the same option to restore normal sync functionality.
Clear Windows Credentials for Office and OneDrive
Removing corrupted cached credentials can fix authentication errors that trigger the Access Denied message when opening files.
Reset the OneDrive Application
Executing the reset command completely clears the local sync state of OneDrive, resolving stubborn file access issues without deleting your actual files.

Frequently Asked Questions
Why does PowerPoint say Access Denied but Word and Excel work normally?
This usually happens due to a specific corrupted credential or a synchronization lock that only affects the PowerPoint application's local cache. Because Word and Excel manage their own temporary caches, they often remain unaffected by PowerPoint's sync lock.
Will resetting OneDrive delete my personal files?
No, resetting the OneDrive sync application does not delete any of your files. It only resets the background application settings and forces a full re-sync of your file metadata to fix hidden access and permission issues.
How do I temporarily unlink my OneDrive account?
Right-click the OneDrive cloud icon in the taskbar, select the gear icon to open Settings, go to the Account tab, and click 'Unlink this PC'. Your local files will remain on your device, and you can sign back in at any time to resume syncing.
