Why full-Chromium Edge means end times for IE Microsoft's decision to adopt the Chromium open-source code to power its Edge browser could mean a sooner-than-expected end to support for Internet. The IE Mode feature made its first appearance in Edge build 77.0.200.0. It was opening a new tab that was simply redirecting its URL to the Internet Explorer browser. Starting in Dev build 77.0.211.1, the ability to open web sites in Internet Explorer mode was finally working properly in a new tab inside the Edge browser. It’s been ages since I’ve blogged, so it was about time to write something new. I’ve been using Microsoft’s new Edge browser ever since the developer build came out, and one it’s best features (at least for IT professionals) is its IE-mode: the possibilty to open certain sites in a tab that runs the Internet Explorer rendering engine. We adopted the Chromium open source project in the development of Microsoft Edge to create better web compatibility for our customers, and less fragmentation of the web for all web developers. We are continuing our commitment to be an active contributor to the Chromium project. Microsoft Edge is the best browser for shopping. Microsoft Edge is the only browser with built-in tools to help you save time and money when shopping online.
-->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.
Note
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:
- 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'
Note
We only process one Enterprise Mode Site List. The Microsoft Edge site list policy takes precedence over the Internet Explorer site list policy.
- All Intranet sites when the Send all intranet sites to Internet Explorer group policy is 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)
- Browser Helper Objects
- Internet Explorer settings and Group Policies that affect the security zone settings and Protected Mode
- The F12 developer tools for IE, when launch 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 affect the navigation menu (for example - search engines, and home pages.)
- IE11 or Microsoft Edge F12 developer tools

Prerequisites
The following prerequisites apply to using Microsoft Edge with IE mode.
Important
To ensure success, install the latest updates for Windows and Microsoft Edge. Failure to do so will likely cause IE mode to fail.

Important
** 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.
