Improve user experience and performance by supporting only modern browsers.

Feature details

With Internet Explorer support ending August 17, 2021, the Unified Interface web browser will start warning users who are running Internet Explorer by using the app message bar. The message will be shown each time the session starts and can be dismissed. Users who move to Microsoft Edge (Chromium) or another modern browser will see their performance improve as much as doubled compared to Internet Explorer, and they'll have a more consistent experience.

Administrators who open either the Power Platform admin center or the classic Advanced Settings and have users within the organization using Internet Explorer will see a warning message. After all users have stopped using Internet Explorer, we'll remove the message for those organizations.

Starting in 2022 release wave 1, Internet Explorer and classic Microsoft Edge browsers will be blocked from opening Unified Interface. This will let us further improve the experience by adding browser enhancements that aren't possible on these deprecated browsers. Leading up to the blocked experience, an app error message will be shown to users of Internet Explorer.

To further improve user experience, 2021 release wave 2 will include user warnings for older browsers. Based on performance investigations, we see that use of older, unsupported browsers have performance issues not seen in the latest version of the same browser. For this release, we'll show users a warning message when they're using browser versions older than Microsoft Edge (Chromium) 83, Chrome 83, and Firefox 76. These browsers were all released in May 2020. Future twice-a-year releases will move up the version that shows warnings.
