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, before it would open the IE Browser separately and gave a message in Edge to reinstall Edge with admin rights. I have IE Mode enabled through the registry by setting InternetExplorerIntegrationLevel = 1 and SendIntranetToInternetExplorer = 1
Anyway, now that it opens in an actual tab in Edge, Internet Mode seems to flip-flop between on and off with every page click. For example going to our Intranet home page, IE Mode is turned on. When I click on a link within the Intranet page, IE mode turns itself off. When I click another link within the Intranet page, IE mode turns itself on again. If after clicking a link IE mode is turned off, clicking the refresh button turns it back on again. No matter how many times i click the refresh button, IE mode stays on, until I click another link within the Intranet page.
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.

Unfortunately, we have the same issue. Do you use self-signed certificate or authority issued certificate on your Intranet domain?

bmoteria 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.
It still flips with Microsoft Edge Dev Build 79.0.301.2
- Still flips on page navigations in build 79.0.279.0.
