Microsoft 365 apps say farewell to Internet Explorer 11 and Windows 10 sunsets Microsoft Edge Legacy

August 17, 2021: Support is now unavailable for Microsoft 365 apps and services on IE11. Additionally, you should expect no new features when accessing Microsoft 365 apps and services on IE11 and that the daily usage experience for users could get progressively worse over time until the apps and services are disconnected. Banners will be used to communicate and alert users to upcoming changes in experience, such as app or service disconnection and/or redirection.

July 23, 2021: Beginning August 17, 2021, Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE11) and users may have a degraded experience, or be unable to connect to, those apps and services. These apps and services will phase out over weeks and months to ensure a smooth end of support, with each app and service phasing out on independent schedules.
