Question details

Users receive an 'unauthenticated' error message preventing them from deleting pictures stored in OneDrive.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Attempting to delete pictures or files from OneDrive cloud storage.
Observed behavior: The system blocks the deletion process and displays an 'unauthenticated' error, likely due to credential, network, or sync client issues.

Before you start

Verify whether you are using a personal OneDrive account or a work/school account, and try signing in through the OneDrive web portal first to see if the issue is limited to the desktop client.

Solution 1Recommended

Reset the OneDrive Client and Re-authenticate

Resetting the OneDrive app clears local cache and forces the system to prompt for fresh authentication credentials.

Often, the connection between the OneDrive client and Microsoft servers becomes stale. Resetting the app forces a complete sync and re-authentication without losing your local files.

Open Run Dialog

Press the Windows key + R on your keyboard to open the Run dialog box.

Execute Reset Command

Type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter.

Restart OneDrive

Wait for the OneDrive cloud icon to disappear and reappear in the system tray. If it doesn't reappear after a few minutes, open the Start menu, search for OneDrive, and launch it manually.

Sign In Again

Follow the prompts to enter your account credentials and re-authenticate your session before attempting to delete the pictures again.

Web Deletion Alternative: If you are still unable to delete files in the app, log into onedrive.com via a web browser to delete the pictures directly from the cloud.

Solution 2

Reset Network Configuration and Check Proxy Settings

Misconfigured network settings, proxy servers, or corrupt Winsock catalogs can block OneDrive from properly authenticating with Microsoft servers.
