How to Fix OneDrive Error 0x8004e4be

If you are experiencing OneDrive Error Code 0x8004e4be, the local sync client is failing to authenticate with Microsoft’s cloud infrastructure due to a security handshake failure. This is often caused by a timestamp mismatch between your computer and Microsoft’s OAuth2 login servers, or stale tenant credentials cached on your local device.

This article details the causes of the 0x8004e4be error and provides steps to resolve it on Windows and macOS.

What Causes OneDrive Error 0x8004e4be?

This security handshake failure typically occurs under the following circumstances:

1. System Time Discrepancies: The local system clock is off by more than 5 minutes, causing security tokens to be rejected as expired or invalid.
2. Expired Multi-Factor Authentication (MFA): Stale authentication states inside the Windows Access Work or School interface or macOS Keychain that fail to trigger MFA prompts.
3. Corrupted Security Descriptors: Glitches in Windows system directories (cldflt.sys or DLLs) that block the app’s secure sandbox.
4. App Sandbox Failures: Cache corruption in the OneDrive database folder preventing reading of local authentication states.

Detailed Steps to Resolve Error 0x8004e4be

Method 1: Sync Your System Clock via command line

A clock difference is the most common reason for authentication failures. You can force-sync your system time with the internet time servers.

1. Right-click the Start menu and choose Terminal (Admin) or Command Prompt (Admin).
2. Run the following commands:

   net start w32time
   w32tm /resync

3. Close the command prompt and check if the clock matches the exact current local time.

Method 2: Disconnect and Reconnect Stale Work or School Accounts

If your account belongs to an organization, a corrupted device register state can block OneDrive.

1. Press Windows Key + I to open Settings.
2. Go to Accounts > Access work or school.
3. Select your organization’s account and click Disconnect.
4. Restart your computer, return to this menu, and click Connect to sign back in.
5. Launch OneDrive and log in.

Method 3: Reset the OneDrive Database Cache

Purge the app files causing synchronization hangs:

1. Press Windows Key + R to open the Run window.
2. Copy and paste:

   %localappdata%\Microsoft\OneDrive\onedrive.exe /reset

3. Manually launch OneDrive after a couple of minutes.

Method 4: Run SFC and DISM System Repairs

If the cloud filter system driver is corrupted:

1. Open Command Prompt as Administrator.
2. Run:

   sfc /scannow
   DISM /Online /Cleanup-Image /RestoreHealth

Method 1: Force Sync Date & Time

Mac security frameworks will reject connection handshakes if your system clock is incorrect.

1. Click the Apple menu > System Settings > General > Date & Time.
2. Toggle off Set time and date automatically, then toggle it back On.
3. Ensure the Source server is set to time.apple.com.

Method 2: Clear Application Sandboxed Container Configs

Purging the plists resolves corrupted tenant token blocks.

1. Open Terminal (located in /Applications/Utilities/).
2. Execute:

   killall OneDrive
   defaults delete com.microsoft.OneDrive-mac
   rm -rf ~/Library/Containers/com.microsoft.OneDrive-mac

3. Open OneDrive from your Applications folder.

• Disconnected and reconnected any stale “Access Work or School” accounts.
• Reset the OneDrive client using the /reset terminal command.
• Checked that system files are healthy using SFC and DISM commands.
• Toggled and refreshed macOS Date & Time settings.
