Internet Explorer mode FAQ


Microsoft Edge with Internet Explorer mode will officially replace the Internet Explorer 11 desktop application starting next year. On June 15, 2022, the Internet Explorer 11 desktop application will be retired, meaning it will go out of support. Afterwards, the Internet Explorer 11 desktop application will be disabled on specific versions of Windows 10. Internet Explorer mode will continue to be supported in Microsoft Edge so that you can continue to access your legacy, Internet-Explorer based sites and apps.

We highly recommend you start transitioning to Microsoft Edge with IE mode as soon as possible to avoid potential business impact. Site discovery, deployment, and testing can take multiple months. Take your first steps using the Getting Started guide.

This retirement impacts the Internet Explorer 11 desktop application delivered via the semi-annual channel (SAC) for Windows 10 client SKUs (version 20H2 and later) and Windows 10 IoT (version 20H2 and later). Windows 10 LTSC, Windows 10 Server, Windows 7, and Windows 8.1 are excluded. For a full list, please see our full FAQ.

IE mode support follows the lifecycle of Windows client, Server, and IoT releases at least through 2029. Additionally, Microsoft will give one year of notice before retiring the IE mode experience when the time comes. For more information, please see our FAQ.

We offer a variety of support options. If you have Microsoft Unified Support, you can reach out to that support service for help with the transition. There’s also FastTrack, which is available at no additional charge to customers with 150 or more paid seats of Windows 10.

We also recommended looking at our Getting Started guide.

Microsoft Edge is built on the Chromium open-source project to provide world-class compatibility for modern sites and apps. Internet Explorer mode provides compatibility for your legacy sites and apps by supporting Internet Explorer functionality like all document and enterprise modes, Active X controls (such as Java or Silverlight), and more.

We also offer the App Assure program in case a compatibility issue does arise when moving from Internet Explorer to Microsoft Edge. The App Assure promise is this: if your web apps and sites work on Internet Explorer 11, supported versions of Google Chrome, or any version of Microsoft Edge (including Microsoft Edge Legacy), those web apps and sites should work on Microsoft Edge. If an issue arises, you can either request assistance or email us (ACHELP@microsoft.com) for remediation support at no additional cost. You can also read more about App Assure and Microsoft Edge in this blog.

The new Cloud Site List Management experience is now available in public preview, with general availability following. For more information, please see our Docs page.

We recommend that you disable the Internet Explorer 11 desktop application prior to its retirement on June 15, 2022 as part of your change management process to help users move to Microsoft Edge.
