Microsoft will truly, finally kill off Internet Explorer in June 2022
Microsoft 365 and other apps will end support for the browser in August.
It's been a long time coming. Microsoft has, at long last, announced when it will pull the plug on Internet Explorer. The company will retire the IE 11 desktop app on June 15, 2022, on most versions of Windows 10.
The move won't affect the Windows 10 Long-Term Servicing Channel, which is used for devices that stay the same over time, such as MRI machines and air traffic control systems. Nor will the retirement affect Server Internet Explorer 11 desktop applications or the MSHTML (Trident) engine. For the most part, though, Internet Explorer will be put out to pasture in a little under 13 months.
Internet Explorer has been part of the Windows fabric for over a quarter of a century. But since the introduction of Edge in 2015, Microsoft has been slowly winding down the old browser. It ended support for previous versions in 2016. Microsoft 365 and other apps will stop supporting IE 11 on August 17th.
Microsoft has urged users who are still clinging onto IE 11 to move to Edge (or another browser, if you prefer) before it ends support next June. Edge has a built-in Internet Explorer mode for websites that still need IE. Many organizations still use old apps and sites that don't really work with modern browsers, so that mode will come in useful. Microsoft says it will support Edge's IE mode at least until the end of 2029, giving orgs and IT departments several more years to transition away from those old web apps.
