What is Internet Explorer (IE) mode?
The Internet Explorer 11 desktop application has retired and is out of support as of June 15, 2022 for certain versions of Windows 10.
- You can still access older, legacy sites that require Internet Explorer with Internet Explorer mode in Microsoft Edge. Learn how >
- The Internet Explorer 11 desktop application will progressively redirect to the faster, more secure Microsoft Edge browser, and will ultimately be disabled via Windows Update. Disable IE today>
We created Internet Explorer (IE) mode in Microsoft Edge for organizations that still need Internet Explorer 11 for backward compatibility with existing websites but also need a modern browser. This feature makes it easier for organizations to use one browser, for legacy web/apps or for a modern web/app. This article provides an introduction to using Microsoft Edge with IE mode.
For an advanced configuration guide, see Configure IE mode for Microsoft Edge.
This article applies to Microsoft Edge version 77 or later.
What is IE mode?
IE mode on Microsoft Edge makes it easy to use all of the sites your organization needs in a single browser. It uses the integrated Chromium engine for modern sites, and it uses the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites.
When a site loads in IE mode, the IE logo indicator displays on the left side of navigation bar. You can click the IE logo indicator to display additional information, as shown:
Only those sites that you specifically configure (via policy) will use IE mode, all other sites will be rendered as modern web sites. For a site to use IE mode, you need to either:
- List the site in the Enterprise Mode Site List XML defined in one of these policies:
- Microsoft Edge 78 or later, "Configure the Enterprise Mode Site List"
- Internet Explorer, "Use the Enterprise Mode IE website list"
We only process one Enterprise Mode Site List. The Microsoft Edge site list policy takes precedence over the Internet Explorer site list policy.
- Configure the Send all intranet sites to Internet Explorer group policy and set it to Enabled (Microsoft Edge 77 or later.)
IE mode supports the following Internet Explorer functionality
- All document modes and enterprise modes
- ActiveX controls (such as Java or Silverlight). Note: Silverlight reaches end of support on October 12, 2021.
- Browser Helper Objects
- Internet Explorer settings and group policies that affect security zone settings and Protected Mode
- F12 developer tools for IE, when launched with IEChooser
- Microsoft Edge extensions (Extensions that interact with the IE page content directly are not supported.)
IE mode doesn't support the following Internet Explorer functionality
- Internet Explorer toolbars
- Internet Explorer settings and group policies that control the navigation menu.
- IE11 or Microsoft Edge F12 developer tools
The following prerequisites apply to using Microsoft Edge with IE mode.
To ensure success, install the latest updates for Windows and Microsoft Edge. Failure to do so will likely cause IE mode to fail.

** Windows 7 and Windows Server 2008 R2 will be supported by Microsoft Edge even after those operating systems go out of support. In order for IE mode to be supported on these operating systems the devices will need to have the Extended Security Updates for Windows 7. We recommend that you upgrade to a supported operating system as soon as possible in order to remain secure. Support for Microsoft Edge with the Extended Security Updates should be considered a temporary bridge to getting to a supported OS state.
