You can configure Internet Explorer to open directly within Microsoft Edge (IE mode). You can also configure Internet Explorer to open with a standalone Internet Explorer 11 window. Most users prefer when sites open directly within Microsoft Edge in IE mode.
Enable Internet Explorer integration using Group Policy
Click User Configuration/Computer Configuration > Administrative Templates > Microsoft Edge.
Double-click Configure Internet Explorer integration.
Select Enabled.
Under Options, set the dropdown value to
Internet Explorer mode if you want sites to open in IE mode on Microsoft Edge
Internet Explorer 11 if you want sites to open in a standalone Internet Explorer 11 window (This option will not be supported after June 15, 2022 when the Internet Explorer 11 desktop application will be retired and go out of support. After June 15, 2022 when IE11 will no longer be available, this option will behave the same as the Internet Explorer mode option.)
None if you want to stop users from configuring Internet Explorer mode via edge://flags or through the command line
Note
Setting the policy to Disabled implies IE mode is disabled by policy, but can be set through edge://flags or command line options.
Click OK or Apply to save this policy setting.
Redirect sites from Microsoft Edge to IE mode
There are two options for identifying which sites should open in IE mode:
Configure the Enterprise Mode Site List (Microsoft Edge, version 78 or later) This policy lets you create a separate Enterprise Mode Site list for Microsoft Edge. Enabling this policy overrides the settings in the "Use the Enterprise Mode IE website list" policy, if "Configure Internet Explorer integration" is enabled. Disabling or not configuring this policy doesn't affect the default behavior of the "Configure Internet Explorer integration" policy.
Note
It is not mandatory to configure the Microsoft Edge policy. Many organizations use this as an override, allowing them to target the current Site List at all users with the IE policy, and more easily target an updated version to pilot uses with the Microsoft Edge policy.
Local file: file:///c:/Users/<user>/Documents/sites.xml
Click OK or Apply to save these settings.
Configure using the Configure the Enterprise Mode Site List policy
You can also configure IE mode with a separate policy for Microsoft Edge. This additional policy allows you to override the IE site list. For example, some organizations will target the production site list to all users. You can then deploy the pilot site list to a small group of users using this policy.
Create or reuse a Site List XML
All sites that have the element <open-in>IE11</open-in> will now open in IE mode.
Open Group Policy Editor.
Click User Configuration/Computer Configuration > Administrative Templates > Microsoft Edge.
Double-click Configure the Enterprise Mode Site List.
Select Enabled.
Under Options, type the location of website list. You can use one of the following locations:
Local file: file:///c:/Users/<user>/Documents/sites.xml
Click OK or Apply to save these settings.
Configure all intranet sites
IE mode can be configured as for all sites in the Local Intranet zone. You can remove individual sites from IE mode using an Enterprise Mode Site List.
Note
The Local Intranet zone contains explicitly added sites, but also assigns sites to this zone using heuristics. This can include dotless host names (e.g. https://payroll) and sites that the proxy configuration script configures to bypass the proxy. If an external party controls DNS or proxy, they could potentially force websites into IE mode.
Open Local Group Policy Editor.
Click User Configuration/Computer Configuration > Administrative Templates > Microsoft Edge.
Double-click Send all intranet sites to Internet Explorer.
Select Enabled, and then click OK or Apply to save the policy settings.
Redirect sites from IE to Microsoft Edge
You can prevent your users from using Internet Explorer for sites that don't need it. Internet Explorer can automatically redirect sites to Microsoft Edge if they aren't on your site list.
Open Group Policy Editor.
Click User Configuration/Computer Configuration > Administrative Tools > Windows Components > Internet Explorer.
Double-click Send all sites not included in the Enterprise Mode Site List to Microsoft Edge.
Select Enabled
Click OK or Apply to save these settings.
Double-click Configure which channel of Microsoft Edge to use for opening redirected sites.
Select Enabled.
Under Options, select your top three choices for the channel to use - Internet Explorer will redirect to the highest ranked choice that the user has installed on that device:
Microsoft Edge Stable
Microsoft Edge Beta version 77 or later
Microsoft Edge Dev version 77 or later
Microsoft Edge Canary version 77 or later
Microsoft Edge version 45 or earlier
Click OK or Apply to save these settings.
Tip
To find sites that you need to add to your IE mode site list, see Configure IE mode for Microsoft Edge guide. If you already have a site list, the tools in this guide will help you apply it to the right users.
