Question details

Users experience a blank sharing pop-up window when trying to share OneDrive files from File Explorer in an environment where AppLocker policies are deployed.

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Sharing a file or folder using OneDrive from File Explorer while AppLocker is enforcing application restrictions.
Observed behavior: The OneDrive sharing pop-up window appears completely blank instead of displaying the sharing options and permissions.

Before you start

Ensure you have administrative privileges or access to your Active Directory Group Policy settings, as verifying or adjusting AppLocker policies requires elevated permissions.

Solution 1Recommended

Restart and Reset the OneDrive Client

Resolve temporary background glitches causing the blank sharing window by cleanly restarting or resetting the OneDrive application.

Before modifying complex AppLocker group policies, it is best to ensure the OneDrive client itself is not experiencing a caching issue or temporary freeze.

Quit OneDrive

Right-click the OneDrive cloud icon in your Windows system tray (taskbar) and select 'Quit OneDrive' or 'Close OneDrive'.

Restart the computer

Reboot your system to clear any temporary background process conflicts that might be interfering with the sharing UI.

Reset OneDrive

If the issue persists after a reboot, press the Windows Key + R, type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' into the Run dialog, and press Enter to reset the application cache.

Solution 2

Request Exact Allowlist Entries from Microsoft Support

Since specific underlying paths for the sharing pop-up can change, contact Microsoft directly to get the exact paths needed for your AppLocker whitelist.

Frequently Asked Questions

Why does AppLocker block the OneDrive sharing pop-up?

AppLocker restricts unauthorized applications and scripts from running. If the specific internal path, dependency, or background process used by the modern OneDrive sharing UI isn't explicitly whitelisted in your Group Policy, the window will fail to load its contents and appear blank.

Does resetting OneDrive delete my stored files?

No, resetting the OneDrive desktop app only refreshes the application's synchronization settings and clears its local configuration cache. Your files safely remain in your cloud storage and on your local drive.

Where can I find my current OneDrive version?

Click the OneDrive icon in your system tray, select the Help & Settings gear icon, click Settings, and navigate to the 'About' tab. Your current version number will be displayed there.

How do I access the Microsoft 365 Admin Center to submit a ticket?

You need global or support administrator credentials for your organization. Go to admin.microsoft.com, log in with your admin account, and navigate to the 'Support' section on the left sidebar to create a new service request.
