End of Support for Teams Web App on IE11

As Microsoft work to finish the move to Microsoft Edge, the new version of Edge that is, more and more services are becoming unsupported on Internet Explorer. Internet Explorer 11 is now considered by Microsoft to be a legacy browser and all efforts for functionality and supportability are going into Microsoft Edge (Edge Chromium) going forward.

A big step in this process is the end of support for Microsoft 365’s golden child at the moment – Microsoft Teams. As of the 30th of November 2020, the Microsoft Teams web app will no longer be supported on Internet Explorer 11. This is the first step towards removing support for Microsoft 365 apps and by August 2021, all Microsoft 365 apps will cease to support Internet Explorer.

What do I need to do?

The good news is that it’s very easy to upgrade to the new Microsoft Edge browser! There are GPOs and deployment methods available to you. It is also available as part of a standard Windows update to all Windows 10 (1803 and higher) devices. For downlevel devices, new Edge can be downloaded here.

If you haven’t already deployed new Edge, then now is the time to do it. The browser performs brilliantly and is leaps and bounds ahead of the classic Microsoft Edge and Internet Explorer. Personally I’ve switched from a longtime Google Chrome user fully to Microsoft Edge this year and haven’t looked back.

Any required version of IE can be kept on the machine for legacy web apps or line of business apps that don’t support Edge or Chrome but for the Microsoft 365 web apps, it’s important to plan this upgrade now if you haven’t already!
