Step-by-Step
- Check Your Internet Connection: Ensure your device is connected to the internet with a stable connection. Restart your router if necessary to resolve any network issues that might be causing the error.
- Pause and Resume OneDrive: Right-click the OneDrive icon in the taskbar notification area and select ‘Pause syncing’ for a few minutes. Then, click on it again and choose ‘Resume syncing’. This can refresh the connection and fix temporary glitches.
- Restart OneDrive: Exit OneDrive completely by right-clicking the icon and selecting ‘Close OneDrive’. Then, reopen it by searching for ‘OneDrive’ in the Start menu and launching the app again. This resets the app and can resolve minor errors.
- Check Date and Time Settings: Incorrect system date and time can cause sync errors. Go to Settings > Time & Language > Date & Time. Enable ‘Set time automatically’ and ‘Set time zone automatically’. Restart OneDrive afterward.
- Reset OneDrive: If the error persists, reset OneDrive by pressing Windows + R to open the Run dialog box. Type ‘%localappdata%\\Microsoft\\OneDrive\\Update’ and press Enter. Then, run the ‘OneDriveSetup.exe’ file from the folder. Follow prompts to reconfigure OneDrive.
- Update Windows and OneDrive: Ensure your Windows OS is up to date by going to Settings > Update & Security > Windows Update. Check for updates and install any available. Also, download the latest OneDrive version from the official Microsoft website.
- Disable Proxy or VPN Settings: Sometimes, proxy servers or VPNs interfere with OneDrive connectivity. Disable any active VPNs or proxies through Settings > Network & Internet > Proxy, and then try syncing again.
- Clear OneDrive Cache: Open File Explorer, navigate to %localappdata%\Microsoft\OneDrive, and delete the ‘Business1’ folder if present. Restart OneDrive afterward to rebuild cache.
