MC220490 – In order to provide the best experience for our customers, we will be focusing our efforts on modern browser support over the coming year. As a result, Microsoft 365 services and applications will no longer support Internet Explorer 11 (IE 11); Microsoft 365 apps and services will be unable to connect, or have a degraded feature experience, when accessed on IE 11. Additionally, the Microsoft Edge Legacy desktop application will experience end of support; after support ends, it will not receive new security updates. The following notification outlines key dates which you should be aware of. Please note that the IE 11 changes are specific to Microsoft 365 services and apps; IE 11 is a component of the Windows operating system and will follow the Lifecycle Policy for the product on which it is installed.
Microsoft Teams (web app)

Microsoft 365 applications and services (excluding Microsoft Teams)
Microsoft Edge Legacy desktop application
How this will affect your organization:
After the dates listed above, Microsoft 365 apps and services will need to be accessed via the new Microsoft Edge, another supported browser, or through an applicable Win-32 app (if available). The new 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 the new Microsoft Edge through Internet Explorer mode.

After March 9, 2021, the Microsoft Edge Legacy desktop application will no longer be supported and will not receive new security updates. Move to the new Microsoft Edge before that date to ensure your organization is using an up-to-date browser.
