Internet Explorer Mode Flip-Flops Between On and Off
With the latest version of Edge Dev Version 78.0.276.2 (Official build) dev (64-bit) on Windows 10 Pro Version 1903 (OS Build 18362.356). It finally properly uses an Edge Tab to go into IE Mode, befo...
Not sure if this will help anyone, but one of the other things I discovered after much frustration was that if you add an enterprise site list or make any changes to it, Edge will take approximately 1-1.5 minutes to load the new list the next time it starts up.
You'll see an EmieSitelist.xml file pop into %localappdata%\Microsoft\Edge[version]\User Data when it's loaded. Prepopulating this file unfortunately does not change this behavior.
To clarify as well, I noticed that even if I specify a sites list in Edge at HKLM\SOFTWARE\Policies\Microsoft\Edge, IE mode will not work properly unless the Enterprise Mode Sites List is configured for Internet Explorer at HKLM\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode).
Interestingly, if you configure the sites list in Edge and then remove the list from your IE Enterprise Mode key or delete the key entirely, it will continue to work on that machine. It just won't work if you start with just the Edge key on a new machine.
Haven't tried this in group policy yet but I expect it would work the same.

Microsoftbmoteria gdube GreatToHearFromYou - Thanks for trying IE mode and for reaching out.
To help us narrow down what's happening it would greatly help if you can collect logs and share back using the following guidance -
- Start Edge with the command line "msedge.exe --enable-logging --v=1 --vmodule=*/dual_engine/*"
- This will create a log in "%localappdata%\microsoft\Edge<Canary/Dev/Beta>\user data\chrome_debug.log"
- The log is human readable and will contain URLs. Please proof read to ensure there is no PII information included before you share back with us.
I have noticed it behaves this way in every configuration I've tried except for enabling the Internet Explorer Enterprise Mode site list and pointing Edge to that list.

Unfortunately using the Enterprise Mode List did not make a difference, it's still flipping back and forth between IE and Edge with every click. Strangely enough that I had to force update the list in edge://compat/enterprise in order for it to accept, it didn't import automatically. Attached I have the Internet Explorer mode diagnostics information found in edge://compat/iediagnostic, just in case it contains crucial information.

AndrewSAIF You can go to edge://compat/enterprise and click on the "Force Update" button to have site list XML changes reflected instantly.
AndrewSAIF GreatToHearFromYou Setting up a site list for Internet Explorer should not be required if you have enabled IE mode and are using this Edge policy - https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#internetexplorerintegrationsitelist.
When the Edge site list policy is enabled, it takes precedence over the IE site list.
Please let us know if you're still experiencing issues.

We configured the enterprise mode site list and it fixes this issue only on my machine (developer machine but treated as normal user machine). Whereas, it doesn't work on system admin's machine. The different between my account and system admin account is that, I have list of trusted sites in Internet Explorer that is managed by IT team. For my system admin, he has to manage his own trusted sites locally in Internet explorer. Still not sure what's causing the issue.
This diagnostic information is of my machine (account).
Thanks for letting us know, much appreciated. Creating the XML file was the next test I was going to do, I now feel more confident about that knowing that it works for you.
