Message Summary

As previously announced (MC306663 – Dec), the future of Internet Explorer on Windows is in Microsoft Edge. Internet Explorer mode (IE mode) provides legacy browser support within Microsoft Edge. Because of this, the IE11 desktop application will be retired on June 15, 2022, on certain versions of Windows 10. This means that the IE11 desktop application will no longer be supported and afterwards will redirect to Microsoft Edge if a user tries to access it.

With 3 months left before retirement, we highly recommend you begin testing your sites in IE mode, followed by disabling the IE11 application completely via policy to ensure readiness.

Note: The IE11 desktop application is not available on Windows 11. To continue using legacy IE-based sites and apps on Windows 11, IE mode in Microsoft Edge must be configured before deploying Windows 11.

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. If you do not set up IE mode before IE11 is retired and disabled, users will lose access to those legacy sites, and you could experience business disruption.

As first seen with the Windows 10 January 2022 C “Preview” release, IE11 now has an in-product banner notifying users of the upcoming retirement. This only shows on Windows versions affected by IE11 retirement. To configure, use the “Hide Internet Explorer 11 Application Retirement Notification” group policy found in the Local Group Policy Editor under Administrative Templates\Windows Components\Internet Explorer.

Note: After June 15, 2022, the IE11 desktop application will be removed from in-scope versions of Windows 10 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, you should set up IE mode in Microsoft Edge as soon as possible because this is a multi-step process.
