| Microsoft Edge - Interoperability and enterprise mode guidance | Microsoft Edge lets you continue to use IE11 for sites that are on your corporate intranet or included on your Enterprise Mode Site List. If you are running web apps that continue to use ActiveX controls, x-ua-compatible headers, or legacy document modes, you need to keep running them in IE11. IE11 offers additional security, manageability, performance, backward compatibility, and modern standards support. | medium | itpro | dansimp | dansimp | dansimp | 10/02/2018 | edge | explore | library | reference |
Interoperability and enterprise mode guidance
Note
You've reached the documentation for Microsoft Edge version 45 and earlier. To see the documentation for Microsoft Edge version 77 or later, go to the Microsoft Edge documentation landing page.
Microsoft Edge is the default browser experience for Windows 10 and Windows 10 Mobile. However, Microsoft Edge lets you continue to use IE11 for sites that are on your corporate intranet or included on your Enterprise Mode Site List. If you are running web apps that continue to use ActiveX controls, x-ua-compatible headers, or legacy document modes, you need to keep running them in IE11. IE11 offers additional security, manageability, performance, backward compatibility, and modern standards support.
Tip
If you are running an earlier version of Internet Explorer, we recommend upgrading to IE11, so that any legacy apps continue to work correctly.
Technology not supported by Microsoft Edge
-
ActiveX controls
-
Browser Helper Objects
-
VBScript
-
x-ua-compatible headers
-
<meta> tags
-
Legacy document modes
If you have specific websites and apps that you know have compatibility problems with Microsoft Edge, you can use the Enterprise Mode site list so that the websites automatically open using Internet Explorer 11. Additionally, if you know that your intranet sites aren't going to work correctly with Microsoft Edge, you can set all intranet sites to open using IE11 automatically.
Using Enterprise Mode means that you can continue to use Microsoft Edge as your default browser, while also ensuring that your apps continue working on IE11.
