Microsoft Says Goodbye to Internet Explorer, Legacy Edge

Microsoft announced today that it will phase out support for Internet Explorer 11 and Legacy Edge on Microsoft 365 over the next year.

“Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE 11) by this time next year,” a new TechCommunity blog post reads. “Beginning November 30, 2020, the Microsoft Teams web app will no longer support IE 11. [And] beginning August 17, 2021, the remaining Microsoft 365 apps and services will no longer support IE 11.”

To be clear, this means that users connecting with IE 11 after those dates will have a degraded experience at best or will no longer be able to connect to Microsoft 365 at worst. IE 11 is the most recent version of IE, and it debuted in 2013.

As for Legacy Edge, the original version of Microsoft Edge that debuted in Windows 10 in 2015, Microsoft says that it will no longer support that browser as of next year as well.

“Now that we’ve shipped the new Microsoft Edge, [sic] and upgraded most of our Windows 10 customers to the new browser, we’re ending support for the Microsoft Edge Legacy desktop app on March 9, 2021,” the post continues. “After March 9, 2021, the Microsoft Edge Legacy desktop app will not receive new security updates.”
