Microsoft takes yet another step towards the dying of Web Explorer


  • When you start IE in Windows 10, a page immediately pops up suggesting Edge.

  • Here is Microsoft's timeline for this series of changes.

Microsoft 365 apps will end support for Internet Explorer 11 by the end of 2021, Microsoft announced in a company blog post this week. This is a big move by the company looking to migrate customers to its more modern Edge browser, even if some companies get stuck on legacy systems running Internet Explorer (IE).

The change begins with the Microsoft Teams web application, which will end IE support on November 30th this year. Microsoft 365 applications will follow by August 17, 2021. This is how Microsoft explained the 365 changes in its blog post:

Customers have a degraded experience or cannot connect to Microsoft 365 apps and services in IE 11. If the experience deteriorates, new Microsoft 365 functions will not be available or certain functions may no longer work if you access the app or service via IE 11.

Even so, Redmond carefully made it clear that IE 11 is not going away. Many companies have proprietary web applications that will only work with this browser and that are unlikely to be deleted entirely in the near future.

Sometimes employees in these organizations use two browsers – IE for those apps and something else like Chrome for everything else. In the blog post announcing these changes, it was stated that Edge's "Internet Explorer Mode" allows Edge to work with some of these apps, although Microsoft obviously cannot guarantee that this will always be the case with every app will be.

In addition to the IE 11 announcements, Microsoft stated that the Microsoft Edge Legacy desktop app (pre-Chromium Edge) "will not receive any new security updates" after March 9, 2021.

Internet Explorer 11 was introduced in 2013 as a core component of Windows operating systems. It will continue to be supported according to the end-of-life guidelines of the operating systems with which it was shipped. In the case of Windows 10, this means that support and security upgrades will end in October 2025.
