End of support for Internet Explorer and old Edge
Microsoft will end support for Internet Explorer 11 as an application in Microsoft 365 services next year.
In exactly one year, on August 17, 2021, Internet Explorer 11 will no longer be supported for Microsoft Web Services, such as Office 365, OneDrive, Outlook, and more.
Microsoft will also end support for Internet Explorer 11 with the Microsoft Teams web application later this year, with support ending November 30.
Although it will take some time for companies to move away from Internet Explorer 11, Microsoft hopes that the new Internet Explorer feature in the Chromium-based Microsoft Edge browser will help a lot. It will continue to allow businesses to access old sites created specifically for Internet Explorer until Microsoft completely stops supporting Internet Explorer 11 in Windows 10.
However, Microsoft's move to stop supporting Internet Explorer 11 in its major web applications is a first step.
In parallel with the end of IE support, Microsoft plans to discontinue support for the existing older version of Microsoft Edge on March 9, 2021.
After the end of the support date, the old version of Edge will no longer receive security updates.
Microsoft aims to bring existing Windows 10 users to the new Chromium-based Edge browser, and states that new devices and future Windows function updates will be included in the new Edge browser.
Microsoft has been working for years to stop using and supporting Internet Explorer.
The company first introduced its new Edge browser (the first Edge) in 2015, codenamed Project Spartan. It was the beginning of the end for Internet Explorer.
