Microsoft Teams is a popular communication tool used by many for work and collaboration. Sometimes, users may encounter an “Error Has Occurred” script error on Windows 11. This issue can prevent Teams from working properly and disrupt your workflow.

Fortunately, this error is usually fixable with some straightforward steps. The solutions range from simple restarts to more detailed troubleshooting. Following these steps carefully will help you get Teams running smoothly again.

This guide will walk you through easy-to-understand instructions to resolve the script error in Microsoft Teams on your Windows 11 PC.

Let’s get started with some quick checks before diving into the fixes.

Quick Note: Prerequisites and Initial Checks

• Check your internet connection: A stable internet connection is essential for Teams to work correctly. Make sure you are connected to the internet.
• Restart Microsoft Teams: Sometimes, simply closing and reopening the app can fix temporary glitches.
• Update Windows 11: Keeping your operating system up to date ensures compatibility with apps like Teams.
• Close other running applications: Conflicts between apps can cause errors, so closing unnecessary programs may help.

Step 1: Clear the Microsoft Teams Cache

Clearing the cache removes temporary files that might be corrupted and causing the script error. This is often the simplest and most effective fix.

1. Close Microsoft Teams completely. To do this, right-click the Teams icon in the system tray and select Quit.
2. Press Windows + R on your keyboard to open the Run dialog box.
3. Type %appdata%MicrosoftTeams and press Enter. This opens the Teams cache folder.
4. Delete all the contents of this folder by selecting all files and pressing Delete.
5. Restart Microsoft Teams and check if the error still appears.

Step 2: Repair Microsoft Teams from Settings

If clearing the cache does not fix the problem, repairing the app can fix corrupted files without uninstalling it.

1. Click on the Start button and select Settings.
2. Go to Apps > Installed apps.
3. Find Microsoft Teams in the list and click the three dots next to it.
4. Select Modify or Advanced options (depending on your Windows 11 version).
5. Scroll down and click Repair. This process will fix corrupted files without deleting your data.
6. Once repaired, open Teams again to see if the error has been resolved.

Step 3: Reinstall Microsoft Teams

If repairing doesn’t work, reinstalling Teams ensures you have a clean installation free from errors.

1. Open Settings > Apps > Installed apps.
2. Find Microsoft Teams, click the three dots, and select Uninstall. Confirm the uninstallation.
3. After uninstalling, restart your computer to clear any leftover files.
4. Visit the official Microsoft Teams website and download the latest version.
5. Install Teams and sign in with your account.
6. Check whether the script error still occurs.

Step 4: Disable Script Debugging in Internet Options

Microsoft Teams uses web technologies that sometimes rely on Internet Explorer settings. Disabling script debugging can prevent script errors from interrupting your experience.

1. Press Windows + S and type Internet Options, then open it.
2. Go to the Advanced tab.
3. Scroll down to the Browsing section.
4. Check the boxes for Disable script debugging (Internet Explorer) and Disable script debugging (Other).
5. Uncheck Display a notification about every script error.
6. Click Apply and then OK.
7. Restart Microsoft Teams and see if the error is resolved.

Alternative Method: Run Teams as Administrator

Sometimes, Teams may require elevated permissions to avoid script errors caused by limited access.

• Right-click the Microsoft Teams shortcut on your desktop or in the Start menu.
• Select Run as administrator.
• Check if the error still appears when running with elevated privileges.
