Last month, we launched a brand new browser built for Windows 10, Microsoft Edge. Microsoft Edge has been built from the ground up to correctly, quickly, and reliably render web pages
, and improve productivity. We understand that many Enterprise customers may have line of business web apps and services that depend on Internet Explorer and the proprietary technologies that it supports. To help support these customers, Windows 10 includes Internet Explorer 11 with Enterprise Mode
, the same version supported on Windows 7 and 8.1. Starting on January 12, 2016, Internet Explorer 11 will be the minimum supported version
to continue to receive security updates and technical support on Windows 7 and Windows 8.1.
Today, we’re going to show you how you can use Enterprise Mode with Microsoft Edge to open Internet Explorer 11 for your business’s sites that require IE’s proprietary technologies. This approach enables your users to run a modern browser designed for better productivity, security
, and rendering web pages—without sacrificing compatibility with legacy line of business applications.
Many of our customers who depend on legacy features only available in older versions of Internet Explorer are familiar with our Enterprise Mode
tools for IE11. Today, we’re extending Enterprise Mode support to Microsoft Edge by opening any site specified on the Enterprise Mode Site List in IE11. IT Pros can use their existing IE11 Enterprise Mode Site List or they can create a new one specifically for Microsoft Edge. By keeping Microsoft Edge as the default browser in Windows 10 and only opening legacy line of business sites in IE11 when necessary, you can help keep newer development projects on track, using the latest web standards on Microsoft Edge. For customers that have significant legacy content, we are also providing the ability to configure any Intranet site to open in IE11 when a user browses to it using Microsoft Edge. This functionality is available as part of Windows 10 and has no additional installation requirements. Find out more about how to use Enterprise mode to improve compatibility in Microsoft Edge
Any sites specified on the Enterprise Mode Site List will open in IE11 automatically—even when navigated to in Microsoft Edge—unless you specifically exclude that site on the list. This action happens without any user input. For example, if Contoso Travel, a line of business application that requires IE’s legacy proprietary technologies, was on the Enterprise Mode Site List or in the Intranet Zone, a user would see the following page when navigating to it in Microsoft Edge while the site is automatically opened in IE11:
The user is prompted to open the website in Internet Explorer 11 (with the option to default to Internet Explorer in the future), but can choose to continue in Microsoft Edge. Selecting “Open with Internet Explorer” will start Internet Explorer 11 and navigate to the current page in a new window (or a new tab if the browser is already running).
Using the Enterprise Mode Site list
For Internet Explorer 11, Enterprise Mode is configured by enabling the Use the Enterprise Mode IE website list
Group Policy. You must then specify the location (URL) of the Enterprise Mode Site List under Options. You can configure Microsoft Edge in a similar way using the Microsoft Edge Allows you to configure Enterprise Site list
Group Policy. That Group Policy specifies the location of the Enterprise Mode Site List for Microsoft Edge. If you enable this policy but do not specify a location for the Enterprise Mode Site List, Microsoft will automatically use the IE11 Enterprise Mode Site List if one exists.

By default, any site that is in the <emie> or <docmode> section of the Enterprise Mode Site List will automatically open in Internet Explorer 11. Additionally, we are introducing a new attribute “DoNotTransition” which allows explicit control over whether Microsoft Edge will open a site in Internet Explorer 11 or not.
||This site on the Enterprise Mode Site List will not transition to Internet Explorer 11 when opened in Microsoft Edge
||This site on the Enterprise Mode Site List will transition to Internet Explorer 11 when opened in Microsoft Edge
||By default any site on the Enterprise Mode Site List will transition to Internet Explorer 11 when opened in Microsoft Edge
The doNotTransition attribute can also be set using the latest version of the Enterprise Site List Manager
. When an existing site list is imported into the latest version each entry will receive an explicit DoNotTransition=”False” setting. This is shown in the UI via the “Open in IE/Internet Explorer” checkboxes. These are found in both the Site Detail and Site List view.

Microsoft Edge and IE11 can share the same Site List, or you can specify separate lists.
Opening Intranet sites in IE11
In addition to using the Enterprise Mode Site List, Microsoft Edge can be configured to send all Intranet sites to Internet Explorer 11. You can do this via the “Sends all intranet traffic over to Internet Explorer” Group Policy. If this policy is configured, it will send all intranet sites to IE11, not just the sites listed in the Enterprise Mode site list. This option provides the same user experience covered earlier. We recommend IT Pros use the Enterprise Mode Site List—and not
this policy—to configure just the minimum set of sites that need to open in IE11, as it will help enable you to modernize your intranet sites for Microsoft Edge more quickly.

When configured, any site that is identified as being on the company Intranet will be automatically opened in Internet Explorer 11 when visited in Microsoft Edge.
For customers that have significant line of business application dependencies on IE11 and legacy IE technologies, you can set IE11 as your default browser on Windows 10 using the Set a default associations configuration file
Group Policy. However, we recommend against this approach to ensure that sites which don’t rely on legacy technologies get the most modern rendering via Microsoft Edge.
How to get started
This feature is available in Windows 10 Build 10240+, so no additional updates are needed. If you are already using Enterprise Mode to address compatibility issues in Internet Explorer 11, all you need to do is configure Microsoft Edge to use your existing Site List. Below are some additional resources.
- Download the new Enterprise Site List Manager Tool – v4.0 (Summer 2015).
- Learn more about Enterprise Modeand how to turn it on.
- Read up on setting up and configuring this functionality on Technet
While we hope that administrators are able to quickly transition to modern web standards and Microsoft Edge, we’re committed to help ease the transition using Internet Explorer 11 and the Enterprise Mode Site List. We’re excited about these new improvements and encourage you to try them out! Let us know your feedback on Twitter @MSEdgeDev
