Microsoft will begin the gradual phase-out of IE11 by ending Teams support for it this fall. Microsoft will stop providing security updates for the desktop version of legacy Edge after next March.
It’s the middle of August 2020 and at this point, Microsoft is still supporting three browsers: Internet Explorer, legacy Edge and the new Edge. But by this time next year, it will be phasing out its support for two of these three. In an August 17 blog post, Microsoft outlined its phase-out timetable for Internet Explorer (IE) and legacy Edge. After November 30,2020, Microsoft Teams will no longer support IE11. And a year from now, August 17, 2021, is the date when Microsoft 365, all up, no longer will support IE11.
