Internet Explorer: No more support for Microsoft accounts and apps

[German]Another small addendum to the Internet Explorer, whose farewell has begun step by step. Starting November 13, 2020, support for Microsoft accounts and Microsoft apps will be dropped. Here is some information on the topic.


Actually, Microsoft would love to bury Internet Explorer right now (see the blog post The perils of using Internet Explorer as your default browser from February 2019).The market share of Internet Explorer on the desktop has already fallen to about 5 percent. But some corporate users depend on this browser, and security updates will be available for several years (until 2029, Microsoft writes that Internet Explorer 11 will be supported as long as support for Windows 7, Windows 8.1 and Windows 10 is offered).


Microsoft recommends using the Edge browser in corporate environments (see here). Redmond is also beginning to shut down support for Internet Explorer. I had already reported a day ago in the blog post Internet Explorer: Compatibility redirect to Microsoft Edge that Microsoft is slowly retiring Internet Explorer. IE 11 now redirects non-compatible web pages to the Microsoft Chromium Edge, so that they will be opened in this browser. In addition, Internet Explorer 11 on Windows 10 displays a notice that the Edge browser is now available.

End of support for Microsoft accounts and apps

German blogger Martin Geuß points out another change in this article. In Internet Explorer, a note should be displayed that some web pages no longer support Internet Explorer. But I have not seen this hint yet.

Martin Geuß writes, that information on the end of support has been sent to corporate customers. The relevant message contains the information that support for Microsoft accounts, apps and various services in Internet Explorer will be discontinued as of November 13, 2020. According to Martin, it is unclear whether this will affect only corporate environments or also private users.

The term 'no longer supported' means that users will still be able to use the browser to log in to Microsoft accounts and use various services such as or OneDrive. However, it is no longer guaranteed that this will work. According to Martin, however, in cases where there are problems with IE 11 when using Microsoft services, there should be a message "Users can no longer use Internet Explorer to access these services".

In a Techcommunity article Microsoft 365 apps say farewell to Internet Explorer 11 and Windows 10 sunsets Microsoft Edge Legacy from August 2020 there is the information that Internet Explorer is gradually losing support for Microsoft 365 Apps (Office). Starting November 30, 2020, IE support for Microsoft teams will end. I had mentioned this in the blog postEnd of support for Internet Explorer 11 in Microsoft 365 and old Edge in Windows 10 from 2021.

Microsoft has published the document here with information about the end of various functions.  

Insecure JScript can be disabled in IE 11

In a Techcommunity post Disabling legacy scripting engine JScript in Internet Explorer dated October 13, 2020, Microsoft notes that the October 2020 security updates also introduced an option to block the execution of JScript (Jscript.dll). This should improve protection against malicious attacks. The options for disabling JScript in Internet Explorer are described in this Microsoft article. Bleeping Computer has published this article with some summary information.
