Quick Note Before You Begin

Before starting the troubleshooting process, please check the following:

• Internet Connection: Ensure your device is connected to the internet. OneDrive requires an active network connection to sync files.
• Windows Updates: Make sure your Windows 11 is up to date. Sometimes system updates fix underlying issues.
• Microsoft Account: Verify you are signed in with the correct Microsoft account linked to OneDrive.
• OneDrive Status: Check if OneDrive servers are down by visiting the Microsoft Service Status page.

Step 1: Restart OneDrive

Restarting OneDrive can often fix temporary glitches causing the error.

1. Click on the OneDrive icon in the system tray (bottom-right corner of your screen). If you don’t see it, click the up arrow to reveal hidden icons.
2. Click Help & Settings (gear icon) and select Close OneDrive.
3. Wait a few seconds, then press Windows key, type OneDrive, and press Enter to launch OneDrive again.

This simple restart refreshes the application and can clear out minor connection issues.

Step 2: Check Your Date and Time Settings

Incorrect date and time settings can cause authentication errors with OneDrive, including error 0x8004de90.

1. Right-click the date and time on the taskbar and select Adjust date and time.
2. Turn on the option Set time automatically.
3. Also, enable Set time zone automatically if it’s not already enabled.
4. If the settings were incorrect, correct them and restart your computer.

Proper date and time settings help your device communicate securely with Microsoft servers.

Step 3: Reset OneDrive

Resetting OneDrive clears cached data and forces the app to re-sync everything. This often resolves more persistent errors.

1. Press Windows key + R to open the Run dialog box.
2. Type %localappdata%MicrosoftOneDriveonedrive.exe /reset and press Enter.
3. Wait about a minute. The OneDrive icon should disappear and then reappear in the system tray.
4. If the icon does not reappear, press Windows key, type OneDrive, and launch the app manually.

This process resets OneDrive without deleting any of your files stored in the cloud.

Step 4: Sign Out and Sign Back Into OneDrive

Sometimes, authentication issues cause error 0x8004de90. Signing out and back in refreshes your account connection.

1. Click the OneDrive icon in the system tray.
2. Go to Help & Settings > Settings.
3. In the Account tab, click Unlink this PC.
4. Confirm your choice and close OneDrive.
5. Open OneDrive again from the Start menu.
6. Sign in with your Microsoft account credentials.

This re-establishes a fresh connection between your PC and OneDrive servers.

Step 5: Check Windows Firewall and Antivirus Settings

Sometimes, firewall or antivirus software blocks OneDrive’s connection. You can temporarily disable these protections to test.

• Open Windows Security from the Start menu.
• Go to Firewall & network protection.
• Temporarily turn off the firewall for your current network.
• If you use third-party antivirus, open its interface and disable protection temporarily.
• Try using OneDrive again to see if the error is resolved.

If disabling firewall or antivirus fixes the problem, add OneDrive as an exception in those programs to prevent future blocks.

Step 6: Update or Reinstall OneDrive

Outdated or corrupted OneDrive installations can cause errors.

To Update OneDrive:

1. Open the Microsoft Store app.
2. Search for OneDrive.
3. If an update is available, click Update.
