- Microsoft 365 web apps will no longer support Internet Explorer 11 in August 2021.
- Microsoft Teams will drop support even sooner, at the end of November, 2020.
- While some features may continue to work, others will stop working or not be available in Internet Explorer 11.
Internet Explorer was already on its way out with the new Microsoft Edge taking its throne, but it's about to get another nail in the coffin. Microsoft announced today that Microsoft 365 apps will drop support for Internet Explorer 11 (IE11) on August 17, 2021 (via MSPU). Microsoft Teams will pull the plug a little sooner, with support for IE11 ending on November 30, 2020.
After the end-of-support dates, Microsoft says that IE11 will have a "degraded experience" with Microsoft 365 apps. This can include being unable to connect to Microsoft 365 apps and services, features not working, and new features not being available.
Customers have been using IE 11 since 2013 when the online environment was much less sophisticated than the landscape today. Since then, open web standards and newer browsers—like the new Microsoft Edge—have enabled better, more innovative online experiences. We believe that Microsoft 365 subscribers, in both consumer and commercial contexts, will be well served with this change through faster and more responsive web access to greater sets of features in everyday toolsets like Outlook, Teams, SharePoint, and more.
The news comes alongside word that support for Microsoft Edge Legacy is ending in March of 2021. Going forward, Microsoft is putting all of its weight behind the new Microsoft Edge, which it built with Chromium at its base. It also has a built-in "IE Mode" that offers compatibility with websites and legacy web apps that were built to work with Internet Explorer.
