Configure Internet Explorer Mode for Edge

Windows devices may exhibit an issue where Internet Options > Trusted Sites becomes inaccessible. As a workaround, you can configure specific sites to use Microsoft Edge's Internet Explorer mode.

To configure Internet Explorer Mode for Microsoft Edge:

1. Download the Microsoft Edge Policy File depending on your platform from here.
   
2. Extract the cab file to a zip file, then extract the zip file to reveal the MicrosoftEdgePolicyTemplates folder.
3. Copy the file MicrosoftEdgePolicyTemplates/windows/admx/msedge.admx to the following directory: c:\windows\PolicyDefinitions.
4. Copy the file MicrosoftEdgePolicyTemplates/windows/adm/en-US/msedge.adm to the following directory: c:\windows\PolicyDefinitions\en-US.
5. Run the Edge browser and in the menu bar enter: edge://compat/SiteListManager. 
6. The Enterprise Site List Manager appears. Click + Add a site.
   
7. The Add a site modal appears. Configure the following options:
   1. In the URL field, enter the URL of the website to be loaded in IE Mode.
   2. Under Open in, select IE Mode.
   3. Click Add to close the modal.
8. Click Export to XML.
9. When the export is complete, under Downloads click on the folder icon next to the file to show the explorer window.
10. Copy the site list XML file to a permanent location (in this case c:\temp\sites).
11. Click Start and in the search bar type edit group policy to run Group Policy Editor.
    
12. In the Group Policy Editor, go to Computer Configuration > Administrative Templates > Microsoft Edge.
13. In the right pane, double-click on Configure Internet Explorer Integration and configure the following settings:
    • Select Enabled
    • Under Options, select Internet Explorer mode.
    • Click OK to close the window.
      
14. In the right pane, double-click on Configure the Enterprise Mode Site List and configure the following settings:
    • Select Enabled.
    • Under Configure the Enterprise Mode Site List, enter the path to the XML file containing the site list copied in step 10. For this example it is: file:///c:/temp/sites/Sites.xml.
      
15. Restart Edge browser.
16. Enter the URL of the website in the site list created previously. The site should load with an Internet Explorer icon to the left of the URL indicating that this site is running in IE Mode.
