Today, we're announcing that Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE 11) by this time next year.  

  • Beginning November 30, 2020, the Microsoft Teams web app will no longer support IE 11.

  • Beginning August 17, 2021, the remaining Microsoft 365 apps and services will no longer support IE 11.

Note

Using Internet Explorer mode in the new Microsoft Edge will not extend IE 11 access to Microsoft 365 apps and services beyond the dates listed above.

Additionally, we will be ending support for the legacy version of the Microsoft Edge desktop app on March 9, 2021, in favor of the new Microsoft Edge. This means that the legacy version of the desktop app will no longer receive security updates.

The recommended browser for Microsoft 365 apps and services is the new Microsoft Edge, which follows the Modern Policy. Go here to download.  

Microsoft will continue to support Internet Explorer 11. Internet Explorer is a component of the Windows operating system and follows the Lifecycle Policy for the product on which it is installed. For more information, go here. For customers who have business-critical,  line-of-business (LOB) apps running on IE 11 today, IE 11 continues to be a supported browser.

For customers using IE 11 to access Microsoft 365 apps and services, or using the legacy version of Microsoft Edge, support options are available to help transition to the new Microsoft Edge.

Customers with Microsoft Unified Support can reach out to that support service for help transitioning to the new Microsoft Edge.

For customers looking to plan, deploy, or adopt Microsoft Edge, there's FastTrack. FastTrack is available to customers with 150 or more paid seats of Windows 10 Enterprise. To get started, submit a Request for Assistance through the FastTrack site.

For customers who prefer to get started on their own, self-guided deployment and configuration materials, including a series from Microsoft Mechanics, are available on Docs.
