Internet Explorer 11 desktop application

  • Timing: The IE11 desktop application will be retired on June 15, 2022
    • Windows 10 LTSC and Server not affected. For a full list of what is in scope for retirement, see the FAQ.
  • Action:

How this will affect your organization:

If your organization has legacy sites and apps with IE dependencies, you will need to set up IE mode so that users can access them through Microsoft Edge. Microsoft Edge, with Internet Explorer mode, is the only browser with built-in compatibility for legacy IE-based sites and apps. It also gives your organization world-class compatibility with a dual engine advantage:

  • Microsoft Edge renders IE-based sites and apps using IE mode.
  • Microsoft Edge renders modern sites and apps using Chromium.

IE mode support follows the lifecycle of Windows Client, Server, and IoT releases at least through 2029. Additionally, Microsoft will give one year notice to deprecate the IE mode experience in-market when the time comes.

Note: After June 15, 2022, the IE11 desktop application will be removed via Windows update. We do not recommend avoiding Windows updates to keep IE11 as Window updates contain critical operating system security patches.

What you need to do to prepare:

To prepare, we recommend setting up Microsoft Edge in your organization. If your organization needs legacy browser support, we recommend setting up IE mode in Microsoft Edge as soon as possible.

  • View the Microsoft browser usage report in the Microsoft 365 Admin center to help size IE usage in your organization. Appropriate permissions required.
  • Use the Getting Started guide to learn how to set up Microsoft Edge in your organization, configure Internet Explorer mode (if needed), and move your end users.
