Fixing OneDrive Script Errors During Windows Sign-In

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Attempting to sign in to the OneDrive desktop application on Windows.
Observed behavior: A script error or JavaScript property error appears and blocks the sign-in process, even though the same account works perfectly on web browsers and mobile devices.

Before you start

Verify that your Windows operating system is fully up to date and that you have administrative privileges to uninstall and reinstall system applications.

Solution 1Recommended

Reinstall the Microsoft OneDrive Application

Since the account works on other platforms, the local Windows installation is likely corrupted and needs to be cleanly reinstalled.

Script errors during sign-in usually indicate that the web components OneDrive uses to render the login screen are damaged. A clean reinstallation of the latest app version will replace these corrupted files and restore functionality.

Uninstall the current OneDrive app

Navigate to Windows Settings > Apps > Installed apps. Scroll down or search for 'Microsoft OneDrive', click the three-dot menu next to it, and select 'Uninstall'.

Download the latest version

Open your web browser, navigate to the official Microsoft OneDrive download page, and download the latest Windows installer file.

Install and sign in

Run the downloaded installer file. Once the installation is complete, launch OneDrive and attempt to sign in with your personal account credentials.

Reinstall the Microsoft OneDrive Application

Contacting Microsoft Support: If the script error persists after a clean installation, capture a screenshot of the exact error message and provide the full details to Microsoft Support for advanced troubleshooting.

Frequently Asked Questions

Why do I get a JavaScript error only on the Windows OneDrive app?

This usually happens when the internal webview components or cached login files used by the Windows desktop client become corrupted. Because web browsers and mobile apps use different, independent authentication methods, they continue to work fine.

Will uninstalling OneDrive delete my locally synced files?

No, uninstalling the OneDrive application will not delete your local files or personal data. Your synced folders will remain exactly as they are on your hard drive, and OneDrive will simply reconnect to them when you reinstall the app.

Can clearing Internet options fix the OneDrive script error?

Yes. The Windows OneDrive sign-in screen sometimes relies on system web components like Edge WebView2 or legacy Internet Explorer settings. Clearing your browser cache and resetting Windows Internet Options from the Control Panel can occasionally resolve these script errors without requiring a full reinstall.
