Before we dive in, a quick note on prerequisites: you’ll need a Windows machine with Microsoft Edge Chromium-based installed, and you’ll want to be on a relatively recent Windows 10/11 build. If you’re in an enterprise environment, you may also leverage the Enterprise Site List XML file or group policy to centrally manage which sites open in IE mode.
Edge IE mode basics: what it is and isn’t
- What it does: IE mode renders a site using the Internet Explorer 11 engine inside Edge, preserving legacy rendering and behavior for older apps while keeping you in a modern browser for all other sites.
- What it doesn’t do: It’s not a full virtualization or separate browser. It’s a rendering mode for specific pages. You still have your modern Edge security, extensions, and updates on the rest of your browsing.
Who should use IE mode
- Businesses with legacy Line-of-Business apps that require older ActiveX controls or specific quirks that modern browsers don’t support.
- Government portals or regulated environments that rely on legacy web tech but want to stay within a modern security posture.
- IT admins who want a safe, auditable way to test compatibility for intranet apps before a full migration.
Section: How to enable IE mode in Edge step-by-step
Note: The UI may vary slightly by Edge version and Windows edition, but the core steps are consistent.
- Check your Edge version and Windows edition
- Ensure you’re on Microsoft Edge Chromium-based and that Windows is up to date.
- In Edge, go to Settings > About Microsoft Edge to confirm the version. If you’re on an older version, update Edge first to ensure IE mode features are available.
- Enable Internet Explorer mode in Edge
- Open Edge and go to Settings.
- Navigate to Default browser.
- Look for the option “Allow sites to be loaded in Internet Explorer mode” and set it to On.
- You may also see an option to “Reload tabs in Internet Explorer mode” — you can enable this later for specific sites you want to test.
- Restart Edge
- After toggling the IE mode switch, close and reopen Edge to make sure the setting sticks.
- Decide how you’ll control which sites open in IE mode
- For personal testing, you’ll manually open a page in IE mode.
- For enterprise deployment, you’ll use the Enterprise Site List a central XML file or Group Policy to automatically route specific sites into IE mode.
- How to load a site in IE mode
- In Edge, navigate to the site you want to view in IE mode.
- If the feature is enabled and the site is eligible, you’ll see a prompt or an option to “Open in Internet Explorer mode” in the Edge menu the three-dot menu or a dedicated IE icon near the address bar.
- Click that option or select “Reload in Internet Explorer mode” if it appears in the address bar. The site will reload inside IE mode until you exit.
- Using the Enterprise Site List for admins
If you’re an IT admin, you can manage a centralized list of sites that should open in IE mode:
- Create an Enterprise Site List XML file that includes all the URLs you want to force into IE mode.
- Deploy the list via Group Policy or Microsoft Intune.
- In Edge settings, point the browser to use that Enterprise Site List so users automatically load listed sites in IE mode.
- Confirm IE mode is active
- When a site is in IE mode, Edge will display an indicator usually a small “IE mode” badge or a blue icon in the address bar. You’ll also notice legacy rendering for that page, which confirms it’s using the IE engine.
- Test your site behavior
- Verify that the legacy functionality ActiveX, old scripts, or specific layout quirks works as expected.
- Check keyboard navigation, form submissions, and any script-dependent features that the site relies on.
Section: How to add a site to IE mode direct workflow
For individual users who don’t manage Group Policy or an Enterprise Site List, here’s a quick workflow:
- Visit the target site in Edge.
- If the site isn’t loading perfectly, look for the IE mode option in the Edge menu or address bar and select “Open in Internet Explorer mode.”
- The page will reload in IE mode, letting you complete your task with compatibility.
- If you find you’ll need IE mode regularly for this site, pin it to your Enterprise Site List or consider enabling “Reload tabs in Internet Explorer mode” so that future opens automatically in IE mode.
Section: Managing compatibility via Enterprise Site List
This is where the real power comes in for organizations.
- Why use Enterprise Site List? It creates a predictable IE mode experience for users, ensuring critical legacy sites render correctly without manual steps.
- How to structure your EM Site List: Each URL can include a Compatibility View setting, a flag to open in IE mode by default, and conditions for when to use specific emulation modes.
- Updating the list: Keep it in a central repository like a shared network location or Azure container and push updates through your deployment tool Group Policy, Intune, or System Center.
Section: VPN considerations for Edge IE mode testing
Using a VPN while testing IE mode-enabled sites can be important in certain scenarios:
- Accessing intranets or test environments that are behind corporate firewalls or on private networks.
- Protecting sensitive credentials and data when you’re connected over public Wi-Fi in coffee shops or coworking spaces.
- Bypassing geo-restrictions or region-based access controls that some legacy apps enforce.
Practical tips for VPN use with IE mode
- Pick a reputable provider: A reliable VPN keeps your traffic encrypted and reduces the risk of data exposure when you’re on public networks.
- Ensure a reliable kill switch: In case the VPN disconnects, a kill switch prevents your real IP from leaking.
- DNS privacy matters: Use a VPN that also protects DNS requests to avoid leaks that could reveal the sites you’re visiting.
- Test performance: IE mode can involve rendering a legacy engine, which may be more sensitive to latency. Run speed tests with and without the VPN to gauge performance.

Section: Best practices for using IE mode with VPNs
- Limit exposure: Only route necessary sites through IE mode and the VPN to minimize risk surfaces.
- Separate tasks: Use different Edge profiles or containers for testing vs. personal browsing to reduce the chance of cross-contamination of cookies or credentials.
- Account for enterprise policies: If you’re in a corporate environment, adhere to IT policies on VPN use and IE mode maintenance. Always test in a controlled environment before rolling out to users.
- Keep software updated: Ensure Edge, Windows, and your VPN client are current to receive security improvements and compatibility fixes.
Section: Security considerations when using IE mode
- IE mode preserves old rendering quirks. it’s not a sandbox replacement. Treat it as a compatibility layer, not a security isolation layer.
- Disable IE mode when you don’t need it. The fewer sites you render in legacy mode, the lower the exposure to older, unpatched vulnerabilities.
- Regularly audit the Enterprise Site List to prune deprecated sites and replace them with modern equivalents where possible.
- Use strong authentication for intranet portals and enforce MFA where possible.
Section: Performance and compatibility trade-offs
- Performance: IE mode can be slower for complex pages due to legacy engine rendering. Expect occasional lags on heavy intranet dashboards.
- Compatibility: The upside is predictable rendering for legacy apps. the downside is occasional quirks when a site tries to use old ActiveX components.
- Browser support: IE mode is supported in Edge on Windows. it’s not available on non-Windows platforms.
Section: Real-world use cases
- Government portals: Many agencies still rely on legacy web apps that require IE mode for day-to-day tasks.
- Enterprise intranets: Finance, HR, and procurement portals often have older tech stacks that haven’t fully migrated yet.
- Software vendors with legacy installers: Some enterprise software requires IE-specific behaviors that are easier to replicate in IE mode.
Section: Troubleshooting common issues
- IE mode not appearing for a site
- Check that IE mode is enabled in Edge settings Default browser > Allow sites to be loaded in Internet Explorer mode.
- If you’re in an enterprise environment, verify that the Enterprise Site List includes the site you’re trying to load in IE mode.
- Site renders incorrectly in IE mode
- Ensure you’re on a supported Edge version and that the site isn’t blocked by enterprise policies.
- Clear cache for the site or test in a private window to rule out caching issues.
- IE mode prompts but won’t reload
- Confirm the site isn’t on a blocked list or being blocked by a third-party extension.
- Restart Edge or reboot the machine as a last resort to reset the IE mode state.
- VPN-related access issues
- Confirm the VPN connection is active and doesn’t drop during the session.
- Check DNS settings to avoid leaks and ensure the VPN route is properly configured for the target network.
Section: Edge IE mode vs legacy Internet Explorer
- Edge IE mode is designed to be a compatibility bridge for sites that require legacy rendering but within a modern, secure browser.
- It’s not a full replacement for upgrading or rearchitecting legacy apps, but it provides a practical interim solution for business continuity.
