Internet Explorer (IE) Mode in Microsoft Edge allows you to open legacy websites that require older technologies such as ActiveX controls, legacy scripting, or IE-specific rendering engines. Many organizations still rely on internal web apps that only function properly in IE Mode.
If IE Mode is not working in Microsoft Edge on Windows 11, you may notice that the option to reload in Internet Explorer mode is missing, the page does not switch engines, or the site still fails to load properly. This issue is usually caused by disabled IE Mode settings, missing optional features, incorrect group policy configuration, or outdated Windows builds.
If IE Mode is not working on your Windows 11 PC, follow the detailed troubleshooting steps below.
How to Fix IE Mode Not Working in Microsoft Edge on Windows 11
Work through each method in order. After completing a step, test IE Mode again.
1. Enable IE Mode in Edge Settings
IE Mode must be enabled manually in Microsoft Edge.
- Open Microsoft Edge.
- Click the three-dot menu (top-right corner).
- Select Settings.
- Go to Default browser.
- Under Internet Explorer compatibility, enable:
- Allow sites to be reloaded in Internet Explorer mode.
- Restart Microsoft Edge.
- Open the desired website.
- Click the three-dot menu again.
- Select Reload in Internet Explorer mode.
If the option appears and works, the issue is resolved.
2. Enable Internet Explorer 11 Optional Feature
IE Mode depends on Internet Explorer components being installed.
- Press Windows + R.
- Type:
optionalfeatures - Press Enter.
- Ensure Internet Explorer 11 is checked.
- Click OK.
- Restart your PC.
If IE 11 components are missing, IE Mode will not function properly.
3. Update Microsoft Edge
An outdated Edge version may not support IE Mode correctly.
- Open Microsoft Edge.
- Click the three-dot menu.
- Select Help and feedback > About Microsoft Edge.
- Edge will automatically check for updates.
- Install any available updates.
- Restart the browser.
Keeping Edge updated ensures compatibility.
4. Configure Group Policy (Windows 11 Pro)
In enterprise environments, IE Mode may require policy configuration.
- Press Windows + R.
- Type:
gpedit.msc - Press Enter.
- Navigate to:
Computer Configuration > Administrative Templates > Microsoft Edge - Locate Configure Internet Explorer integration.
- Set it to Enabled.
- Choose Internet Explorer mode from the dropdown.
- Click Apply > OK.
- Restart your PC.
Policy configuration ensures IE Mode is enforced system-wide.
5. Check Enterprise Mode Site List (If Applicable)
Organizations often use an Enterprise Mode Site List.
- In Group Policy, locate:
Configure the Enterprise Mode Site List - Ensure a valid XML site list path is configured.
- Confirm the website is included in the list.
- Restart Edge.
Without a valid site list, some enterprise setups will not switch to IE Mode automatically.
6. Clear Edge Cache
Corrupted cache files may interfere with rendering.
- Open Edge.
- Press Ctrl + Shift + Delete.
- Select Cached images and files.
- Click Clear now.
- Restart Edge.
Clearing cache ensures the site reloads properly in IE Mode.

- Press Windows + I.
- Go to Apps > Installed apps.
- Locate Microsoft Edge.
- Click the three-dot menu and select Modify.
- Click Repair.
- Restart your PC.
Repair reinstalls Edge without deleting your browsing data.
8. Install Windows Updates
IE Mode relies on system-level components.

- Go to Windows Update.
- Click Check for updates.
- Install available updates.
- Restart your PC.
System updates often fix compatibility issues.
Important Note About IE Mode
Internet Explorer has been retired as a standalone browser, but IE Mode in Microsoft Edge remains supported for legacy compatibility. However, IE Mode is intended for enterprise and legacy web applications—not modern browsing.
If a website still fails in IE Mode, the issue may be related to outdated ActiveX controls, blocked security settings, or server-side configuration.
Conclusion
If IE Mode is not working in Microsoft Edge on Windows 11, the issue is typically caused by disabled IE Mode settings, missing Internet Explorer components, group policy misconfiguration, or outdated browser/system builds. In most cases, enabling IE Mode in Edge settings and ensuring IE 11 optional features are installed resolves the issue quickly.
By following the structured troubleshooting steps above, you should be able to restore IE Mode functionality and access legacy websites without interruption. If the issue persists in an enterprise environment, reviewing group policies and site list configurations may be necessary.
