Internet Explorer Mode broken in Edge Dev Version 80.0.361.9
GreatToHearFromYou dmcaylor There is a known issue being worked on right now which casues IE not to validate a Microsoft signature on a dll shipped with Edge. If you are affected by this bug, you will be find a Microsoft certificate in the "Trusted Publishers" folder in certmgr.msc that matches the one Edge is being signed with. The workaround would be to remove this cert from Trusted Publishers until we get a fix out.
Thank you for finding the offending certificate, and I can confirm that IE Mode is working again after removing this certificate. However, in our environment we've added this certificate to the trusted certificates through GPO, so that Microsoft Teams (which shares this certificate) can run. Our Software Restriction Policies do not allow programs to run from the user profile folder (or anywhere else but the 2 Program Files folders), unless we trust the certificate. Unfortunately Microsoft installs and runs Teams from the user profile folder, thus we need this certificate to stay in place.
So, even though this is a great find, this is unfortunately not a solution. However, now that I know the culprit I will see if we can move Teams to one of the Program Files folders instead, like we have done with OneDrive. But ultimately Microsoft needs to fix the issue.
Shilpa_SubramanianAny word on a permanent fix for this yet?
Edit: I just did a quick search and even using the Teams msi, it will still install in the User Profile folder. I don't get why Microsoft is pushing for this. Skype/Lync is installed in the Programs Files folder and get updated perfectly fine. Anyway, all the more reason that Microsoft has to permanently fix this issue.
GreatToHearFromYou The fix for this issue will ship as part of the Windows update the week of 2/17.
- Morning I am running Win10 1709 x64 + Chrome-Edge Stable channel Version 83.0.478.45. The IE mode has stopped working as per discussion. This impacted one account initially, 2nd account used to logon to machine didn't experience issue. Now the 2nd account has same issue. Edge/IE GPOs are asssigned to machine. I tried removing the cert with matching serial number, however I still see issue.
Please try latest stable Version 83.0.478.54. Perhaps this will help.
