As announced in (MC257152 - May and MC288052 - Sept), the future of Internet Explorer on Windows 10 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. 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 7 months left before retirement, we highly recommend you start preparing for this multi-month transition today. The essential first step—Site Discovery—typically takes 3-4 weeks. Because this step requires active users on your network, we recommend kicking this off before the holiday downtime. Site Discovery identifies legacy-dependent sites in your organization based on user traffic. Don’t delay and get started on your transition today.
Note: IE 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.
Internet Explorer 11 desktop application:
Timing: The IE11 desktop application will be retired on June 15, 2022

IE11 is not available on Windows 11.
To continue using a supported browser, transition to the Microsoft Edge.
To continue using legacy IE-based sites and apps in Windows 10 and Windows 11, you will need to configure those sites and apps to open in Microsoft Edge using Internet Explorer mode.
Start setting up IE mode by performing Site Discovery (3-4 week process depending on the size of your organization). This is also available as part of the Configure IE mode guided experience in the Microsoft 365 Admin Center.
