Updated October 07, 2021: We have updated the content below for additional clarity.
As announced in MC257152 (May 2021), 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 9 months left before retirement, we highly recommend you start preparing today. The essential first step—Site Discovery—typically takes 3-4 weeks.
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.
To continue using a supported browser, transition to the Microsoft Edge.
To continue using legacy IE-based sites and apps, 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.
