Internet Explorer 11 is Being Retired


Today Microsoft 365 announced that the future of Internet Explorer on Windows 10 is in Microsoft Edge. Internet Explorer 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.

How Does This 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.

Reminder: Microsoft 365 apps and services will no longer support IE11 after August 17, 2021; after this date, Microsoft 365 apps and services will be unable to connect, or have a degraded feature experience, when accessed on IE11

How Can You Prepare?

To prepare, we recommend setting up Microsoft Edge in your organization. If your organization needs legacy browser support, you will want to set up IE mode in Microsoft Edge.

  • 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.
