Microsoft to end support for IE 11 in Microsoft 365

Many Computing Center clients use Microsoft 365 applications along with Internet Explorer (IE 11). Some clients integrate IE 11 iwith other 3rd party applications.  Microsoft is planning on discontinuing support for IE 11 and Microsoft 365 in August 2021. It's evident that from a Microsoft perspective, they are supporting Microsoft Edge as their primary browser application going forward.  Below is their general announcement. If you drill down into the links there is further detail.  We can assist you with the transition to Microsoft Edge or any other browser application that will best integrate with your business or organization and users.

 As communicated in MC220490 (August ’20), Microsoft 365 apps and services will be focusing their efforts on modern browser support over the coming year. As a result, Microsoft 365 apps and services will no longer support Internet Explorer 11 (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.

For a full list of Microsoft apps with intentions to end support on IE11, please see this Docs page. 

Please note: The IE 11 changes are specific to Microsoft 365 apps and services. IE 11 remains a supported browser as a component of the Windows operating system and will follow the Lifecycle Policy for the product on which it is installed. 

Microsoft 365 applications and services

  • Timing: Microsoft 365 apps and services will no longer support Internet Explorer 11 after August 17, 2021.
    • Microsoft Teams ended support on Internet Explorer 11 as of November 30, 2020.
  • Action: To access Microsoft 365 apps and services, use Microsoft Edge, another supported browser, or an applicable Win-32 app (if available). 

How this will affect your organization:

After the dates listed above, Microsoft 365 apps and services will need to be accessed via Microsoft Edge, another supported browser, or through an applicable Win-32 app (if available). The Microsoft Edge browser provides a faster, more responsive experience for Microsoft 365 apps and services. You can also still run business-critical, Internet Explorer-based apps and sites in Microsoft Edge through Internet Explorer mode.

What you need to do to prepare:

To address these announcements, upgrade to Microsoft Edge prior to August 17, 2021. Microsoft 365 apps and services will continue to support Microsoft Edge.
