Body

What exactly is Edge IE mode and why should you care when using a VPN?

IE mode in Edge is a compatibility layer that lets you render certain older websites and intranet apps using the IE11 rendering engine inside the Edge browser. For many businesses, this means users can stay in a single browser while accessing apps that require legacy scripts, ActiveX controls, or specific security headers that modern browsers don’t support. From a VPN perspective, IE mode isn’t a VPN feature, but it tightly connects with how you access corporate resources remotely. If your intranet site is only reachable through a VPN, you’ll still want a secure tunnel before loading that site in IE mode. In other words, IE mode helps you stay productive with legacy apps, while a VPN protects the session as you cross the internet.

Key takeaways:

IE mode preserves compatibility without forcing a full browser switch.
It’s widely used in regulated industries where legacy business apps still drive day-to-day operations.
When working remotely, pairing IE mode with a VPN helps ensure that sensitive intranet traffic travels securely.

Industry data indicates that many large organizations still rely on legacy intranet apps, and IE mode provides a bridge to modern browsers without a full rewrite. While precise numbers vary by sector, the trend is clear: IE mode is here to stay long enough for IT teams to migrate gradually, not overnight. This makes understanding how to add a site to IE mode and manage its lifecycle essential for anyone responsible for corporate web apps and remote access.

Prerequisites: what you need before you start

Before you can add sites to IE mode, make sure you have:

A Windows computer with Microsoft Edge Chromium-based installed.
An account with sufficient permissions to change Edge settings and, if you’re deploying site lists enterprise-wide, access to Group Policy or the registry for site lists.
A site that you want to run in IE mode, plus a plan for whether you’ll do this on a per-site basis or via an Enterprise Mode Site List EMS List.
If you’re connecting to corporate intranets, a VPN plan or provider that covers your remote devices NordVPN, for example, can guard traffic when accessing intranet apps remotely.

Tip: If you’re evaluating a VPN for secure remote access while you test IE mode with intranet sites, NordVPN’s current promotion is a popular option for individuals and small teams. It’s the same offer I’d recommend checking out when you’re ready to secure those journeys to your intranet sites.

Step-by-step: enable Internet Explorer mode in Edge

Open Edge and go to Settings

Click the three-dot menu … in the upper-right corner and choose Settings.

Enable IE mode in Edge

Navigate to Default browser or search for “IE mode” in Settings.
Turn on the option that says something like “Allow sites to be reloaded in Internet Explorer mode” or “Let Internet Explorer mode pages load in the new Microsoft Edge.”
You’ll typically need to restart Edge after enabling this.

Verify IE mode is active

Open a site you want to run in IE mode. If the site loads with the IE engine, you’ve got IE mode enabled. If not, double-check the toggle and restart Edge.

What if you’re deploying this across many devices?

Use Enterprise Mode Site List EMS List. This is a centralized XML-based list that tells Edge which sites must open in IE mode automatically.
Configure EMS List via Group Policy Windows or via the registry for non-domain devices.
Test in a staging environment before rolling out to production.

How to add a site to IE mode manual method

If you’re just testing on a single device, you can add sites on the fly:

Open the site you want in Edge.
Click the three-dot menu Settings and more in the upper-right corner.
Choose “Reload in Internet Explorer mode.” Edge will reload the page using the IE11 engine.

If you’re an admin aiming for organization-wide consistency:

Create an EMS List XML with entries like:
Serve this file from an internal web server and point Edge at it via policy:
- For Windows: Configure Group Policy under Administrative Templates > Microsoft Edge > Configure Internet Explorer integration > Internet Explorer mode site list.
- For non-domain devices: Use the registry to point to the EMS List URL.
After deployment, Edge will load the specified sites in IE mode automatically, without manual clicks on each page.

Tips for a smooth rollout:

Start with a pilot group of users and a small set of sites. This helps you catch compatibility issues early.
Maintain a close relationship between your EMS List and your app owners. When apps are updated, you may need to adjust the EMS List entries.
Document the expected user experience: what to expect when an IE mode site loads, what indicators show IE mode is active, and how to exit IE mode if needed.

VPN considerations when using Edge IE mode for legacy apps

Always connect to your corporate VPN before attempting to load intranet sites in IE mode. The VPN creates a secure tunnel, ensuring that sensitive data doesn’t traverse the open internet.
Resolve tunneling strategies:
- Split tunneling: Useful for performance, but ensure sensitive intranet traffic still routes through VPN when accessing intranet sites.
- Full tunneling: Simpler security model, but may impact performance on a home network or mobile connection.
When using VPN with Edge IE mode, ensure your VPN client is compatible with Windows and can co-exist with Edge’s security features. Most modern VPN clients work fine, but it’s worth testing a small set of sites first.
Security posture: Keep Edge up to date, enable Windows Defender, and use MFA for corporate access. IE mode is a compatibility feature, not a security mechanism. your VPN and endpoint protections remain essential.

Personal tip: If you’re testing with sensitive intranet apps, a VPN like NordVPN can help ensure your browser traffic is encrypted, especially on public networks. It’s a quick win while you’re evaluating compatibility and rollout. Microsoft edge free vpn reddit guide to using free VPN extensions, privacy tips, and performance considerations in 2025

Data and statistics to guide expectations

Many large enterprises still rely on legacy intranet apps that require IE-era behaviors. While exact numbers vary by industry, surveys indicate a significant portion of corporate IT teams maintain compatibility layers like IE mode to avoid expensive rewrites.
Edge’s IE mode is designed to be transitional. Microsoft positions IE mode as a bridge for migrations, not a permanent replacement for modern web apps. Plan for a multi-year migration path and use EMS List to manage sites with minimal disruption.
When you pair IE mode with a VPN, the security benefits multiply: you protect data-in-transit and ensure that intranet traffic doesn’t leak to the consumer network, which is especially important for remote or hybrid workforces.

Troubleshooting common issues

Issue: IE mode not loading for a site after enabling the toggle
- Check that the site was added to the EMS List or is being opened with a manual “Reload in Internet Explorer mode.”
- Ensure the Edge version supports IE mode update Edge if needed and restart after enabling the feature.
Issue: Some features don’t render correctly in IE mode
- IE mode uses the IE11 engine, which can render some modern features differently. If a site uses modern CSS/JS heavily, consider a modernization plan or site-specific compatibility tweaks.
Issue: VPN interference with IE mode
- Verify VPN connection is established before loading intranet sites. If you’re using split tunneling, confirm that intranet traffic routes through the VPN. Check for DNS resolution issues when connected to VPN.
Issue: EMS List isn’t applying
- Double-check the registry or Group Policy configuration. Confirm Edge is reading the EMS List URL and that the list is accessible from the devices.
Issue: Exiting IE mode
- Use the site’s browser menu to “Open in Microsoft Edge” or reload in normal mode. For EMS List deployments, changes apply according to the EMS List update cadence.

Security best practices for IE mode users

Always pair IE mode with a modern security stack: up-to-date Edge, OS patches, endpoint protection, and a VPN for remote access.
Minimize exposure: only run legacy sites in IE mode. avoid loading untrusted sites in IE mode.
Regularly review EMS List entries to eliminate stale sites and migrate apps when feasible.
Enforce least privilege: restrict user permissions for editing EMS Lists and rely on IT-approved changes via GPO or central IT management.

IT admin playbook: deploying IE mode at scale

Start with a clear migration plan: list all legacy apps, categorize them by criticality, and set clear milestones for migration or modernization.
Use EMS List for scalable deployments. Keep a controlled XML file hosted on a trusted server and version it like you would any software asset.
Test, monitor, and adjust: create a staging environment to test app compatibility for new Edge builds and IE mode changes. Track user feedback and compatibility incidents.
Provide user training: simple guides on how to use IE mode, what to do if something breaks, and how to exit IE mode when needed.
Documentation: maintain an internal knowledge base with step-by-step instructions for enabling IE mode, adding sites, and responding to common issues.

Alternatives and complementary approaches

Rewriting or modernizing legacy web apps to fully support modern browsers is ideal but takes time and resources.
Remote desktop or virtualized sessions can allow access to legacy apps without running them in a browser, which can be a good interim solution.
If you only need occasional compatibility for a single page, consider using a dedicated IE tab extension or a separate IE-based VM for the most troublesome sites.

Practical quick-start checklist

Verify Edge version supports IE mode and enable the toggle in edge://settings/defaultBrowser.
Decide between per-site loading manual vs EMS List enterprise-wide.
If EMS List, create and host the XML. configure Group Policy or registry to point to the list.
Test a pilot set of sites in IE mode. document any rendering issues.
If remote access is needed, set up VPN rules and verify that intranet traffic is secure.
Communicate steps to end users and provide self-help resources.
Monitor for updates to Edge, EMS List, and VPN clients. plan for migrations away from IE-dependent sites.
