Microsoft will end support for Internet Explorer 11 across its Microsoft 365 apps and services this year. On August 17th, 2021, Internet Explorer 11 will no longer be supported for Microsoft’s online services like Office 365, OneDrive, Outlook, and more. Microsoft already ended support for Internet Explorer 11 with the Microsoft Teams web app on November 30th 2020.
While it is still going to take some time to pry enterprise users of Internet Explorer 11 away, Microsoft is hoping that the new Internet Explorer legacy mode in the Microsoft Edge browser will help. It will continue to let businesses access old sites that were specifically built for Internet Explorer, until Microsoft fully drops support for Internet Explorer 11 within Windows 10. Microsoft’s move to stop supporting Internet Explorer 11 with its main web properties is a good first step, though.
Alongside the support changes, Microsoft is also planning to drop support for its existing legacy version of Microsoft Edge on March 9th, 2021. After the end of support date, the legacy version of Edge will no longer receive security updates. Microsoft has been moving existing Windows 10 users over to its new Edge browser, and the company says new devices and future Windows feature updates will all include the new Edge browser
Microsoft has been working on killing off Internet Explorer usage and support for years now. The company first unveiled its new Edge browser back in 2015, codenamed at the time Project Spartan. It was the beginning of the end for the Internet Explorer brand.
Some customers might be concerned about compatibility when it comes to business-critical apps and sites. Microsoft offers compatibility “peace of mind” with App Assure. The App Assure promise is if customers’ web apps and sites work on Internet Explorer 11, supported versions of Google Chrome, or any version of Microsoft Edge (including Microsoft Edge Legacy), those web apps and sites should work on the new Microsoft Edge.
