To open this page in Internet Explorer mode, reinstall Microsoft Edge with administrator privileges.
It appears to be related to the Internet Explorer patch version. If you go to edge://compat/iediagnostic check to see if Internet Explorer mode API version shows "Not Supported".
If so, you'll need to update your Internet Explorer version. I found that working machines had KB4519974 installed, whereas the broken ones were on an older version of IE. Once I installed KB4519974 and rebooted, it resolved the issue.
MicrosoftPNE77 Hello! There can be a variety of reasons users see this error message.
There have been some past discussions here in the Tech Community. For example:
- Internet Explorer mode issue - Microsoft Tech Community
- Re: Internet Explorer Mode broken in Edge Dev Version 80.0.361.9 - Page 2 - Microsoft Tech Community
If those do not help, I would suggest filing a customer support request: https://support.serviceshub.microsoft.com/supportforbusiness. Support will be able to work with you to get necessary logs and information to investigate your specific issue. Thanks!

Kelly_Y Hello, thanks for your answer and your help.
So far :
I've try to reinstall (as admin) with deleting all Edge and Internet Explorer folders in %APPDATA% ans %LOCALAPPDATA% and registry. And after reinstalling, I've reset edge in the menu.
Problem occurs on Windows 10 and Windows 7 with differents level off updates.
On impacted computers, the "Redirect sites from Microsoft Edge to IE mode" part of the GPO doesn't work either as Internet Explorer keep openning on all sites.
Problem seems to be system wide as it occurs with multiples Windows profiles (AD, local, even new users on the computer).
Application event log show this warning : [40720:39572:0217/185859.790:WARNING:web_contents_internet_explorer_tab_host_observer_win.cc(207)] Creation of Internet Explorer mode tab failed: 3
Not so much information on internet to solve this 😞
I will try to open a Microsoft case.
- Did you find the fix for this problem? I have deployed edge using sccm on all our windows 7 machines and using gpo for IE mode. There are no issues on windows 10 computers. Only on windows 7 and windows sever 2012 vdi.
