Microsoft Edge for iPad Pro™ requires iOS 11.0 or later. Microsoft Edge is supported on the two most recent versions of iOS. When a new version of iOS is released, the Microsoft Edge Operating System requirement becomes the then-current two most recent versions: the new version of iOS and the previous version. Microsoft Edge is the default browser experience for Windows 10 and Windows 10 Mobile. However, if you're running web apps that rely on ActiveX controls, continue using Internet Explorer 11 for the web apps to work correctly. Microsoft Edge seamlessly works with Microsoft 365 management, security, and productivity tools. Take a hands-on tour to experience the security, compatibility, and manageability of the new Microsoft Edge. Edge is based on Chromium and designed to be the.

The feature is known as “IE Mode,” and it has been designed for organizations to load internal sites without using a separate browser or having to redesign the site. The new approach loads the pages within Microsoft Edge like a regular website without using and managing multiple browsers.

If you want to start using it, the version of Microsoft Edge available through the stable channel now includes the “Internet Explorer compatibilities” settings to quickly enable IE Mode and a separate option to open Edge when browsing an incomparable website with Internet Explorer. Alongside the settings, it also possible to use the Group Policy Editor to configure the compatibility mode.

In this guide, you will learn the steps to enable IE Mode to load legacy websites using the Internet Explorer rendering engine on Chromium Edge for Windows 10. (You can also watch this video tutorial to configure the feature.)

How to enable IE mode on Microsoft Edge

Open Internet Explorer sites on Microsoft Edge

On Windows 10, Microsoft Edge also lets you configure the browser so that when someone is using Internet Explorer incompatible or all sites will load within Edge.

  2. Click the Settings and More (ellipsis) button on the top-right corner.

    • Incompatible sites only – IE will still load sites, but websites designed for a modern browser will load in Edge.
    • Always – IE will always switch to Edge to load websites.

Once you complete the steps, when surfing the web in Internet Explorer, websites will open on Microsoft Edge, according to your configuration.

  15. Browse to the following path:

  16. Click the Paste button from the “Home” tab.

  17. In the “admx” folder, inside the “MicrosoftEdgePolicyTemplates” folder, open the language folder that represents your language — for example, en-US.

  18. Select the msedge.adml and msedgeupdate.adml files and click the Copy option from the “Home” tab.

    Quick tip: You only need to copy the “msedgeupdate.adml” file if you also copy the file on step No.12.

    In the above command, make sure to change en-US for the folder that matches your language.

  20. Click the Paste button from the “Home” tab.

Once you complete the steps, the new policies to enable or disable IE Mode on Edge Chromium will install in the Group Policy Editor.

Enable IE Mode on Microsoft Edge

To enable IE Mode on Chromium Edge with Group Policy, use these steps:

  1. Open Start.

  2. Search for gpedit and click the top result to open the Group Policy Editor.

  3. Browse the following path:

  4. Double-click the Configure Internet Explorer integration policy.

  5. Select the Enabled option to enable IE Mode for Microsoft Edge.

  6. Under the “Options” section, select the Internet Explorer mode from the dropdown menu.

  7. Click the Apply button.

  8. Click the OK button.

After you complete the steps, websites will render in compatibility mode, and you’ll notice a familiar IE icon on the left side of the address bar letting you know the website is using Internet Explorer.

These steps enable IE Mode for intranet websites. If you want to load external websites using Chromium Edge, you need to enable and set up the “Configure the Enterprise Mode Site List” policy, which includes the creation of an XML file with the list of domains that you want to load automatically with the Internet Explorer mode.

Update February 11, 2021: This guide has been revised with the steps to configure IE Mode on the Chromium version of Microsoft Edge using the new compatibility settings and updated the process to install the Group Policy templates.
