Quick Note

  • Make sure your internet connection is stable and working properly.
  • Check that you have the latest version of Windows 11 installed.
  • Confirm that OneDrive is updated to its latest version.
  • Ensure your Microsoft account credentials are correct and active.

Step 1: Restart OneDrive and Your Computer

Sometimes, a simple restart can clear temporary glitches causing the error. First, close OneDrive completely.

  • Click the OneDrive icon in the taskbar notification area.
  • Click on the gear icon for Settings, then select Close OneDrive.

After closing, restart your PC. Once restarted, open OneDrive again and see if the error persists.

This step helps because restarting clears temporary data and refreshes network connections.

Step 2: Check Your Internet Connection

OneDrive error 0x8004de40 often happens due to network issues. Check if your internet is working by opening a web browser and visiting a website like microsoft.com.

If websites load slowly or not at all, try these actions:

  • Restart your router or modem by unplugging it for 30 seconds, then plugging it back in.
  • Switch from Wi-Fi to a wired Ethernet connection if possible.
  • Temporarily disable any VPN or proxy you may be using.

OneDrive needs an active and stable internet connection to sync files and sign in.

Step 3: Reset OneDrive

If the problem continues, resetting OneDrive can fix corrupted settings or cache files causing the error.

To reset OneDrive:

  1. Press Windows + R keys to open the Run dialog box.
  2. Type %localappdata%MicrosoftOneDriveonedrive.exe /reset and press Enter.
  3. Wait for OneDrive to reset. The OneDrive icon may disappear and reappear after a minute.

If the icon does not reappear, open OneDrive manually by searching for “OneDrive” in the Start menu and clicking the app.

Resetting removes temporary files and restores OneDrive to default settings without deleting your files.

Step 4: Check Date and Time Settings

Incorrect date and time on your PC can cause authentication errors with OneDrive.

To fix this:

  1. Click the clock on the taskbar and select Date and time settings.
  2. Make sure Set time automatically and Set time zone automatically are turned on.
  3. If they are off, toggle them on and wait a moment for Windows to update the settings.

This ensures your system time matches Microsoft’s servers, which is necessary for secure sign-in.

Step 5: Sign Out and Sign In Again

Sometimes, your OneDrive account session may be corrupted. Signing out and then signing back in can refresh your credentials.

To do this:

  • Click the OneDrive icon in the taskbar and select Settings.
  • Go to the Account tab and click Unlink this PC.
  • Confirm the unlink and close OneDrive.
  • Open OneDrive again and sign in with your Microsoft account credentials.

This step helps to reset the connection between your PC and your OneDrive account.

Step 6: Disable Firewall or Antivirus Temporarily

Sometimes, your firewall or antivirus software may block OneDrive from connecting to the internet.

To check if this is the cause:

  1. Temporarily disable your firewall or antivirus.
  2. Try to open OneDrive and check if the error still appears.
  3. If OneDrive works, add it to the firewall or antivirus exception list.

Remember to re-enable your firewall or antivirus after testing to keep your PC protected.

Step 7: Update Windows and OneDrive

An outdated system or OneDrive app can cause compatibility problems.

To update Windows 11:

  1. Open Settings via the Start menu.
  2. Go to Windows Update and click Check for updates.
  3. Download and install any available updates, then restart your PC.

To update OneDrive:

  1. Visit the official OneDrive download page.
  2. Download and install the latest version.

Alternative Method: Use OneDrive Web Version

If the error persists and you need immediate access to your files, you can use the OneDrive web interface:

  • Open your web browser.
  • Go to onedrive.live.com.
  • Sign in with your Microsoft account.
  • Access, upload, or download your files directly from the browser.

This method bypasses local app issues but does not sync files to your PC automatically.
