Microsoft EDGE browser ignoring Enterprise Mode list

Question

Since EDGE seems to be the \"default\" browser for Windows 10, we need a way to \"force\" EDGE to open our website in IE mode or at least direct the user to open the website in

Answer 1

So far the articles https://technet.microsoft.com/en-us/library/mt270205.aspx and https://msdn.microsoft.com/en-us/library/Dn872481.aspx are misleading and don't fully work on my machine.
There are two options I was able to get to work.

1. Group policy & XML site list
   The articles say to use "Administrative Templates > Windows Components > Internet Explorer > Use the Enterprise Mode IE website list. This did not work for me.
   BUT "Administrative Templates > Windows Components > Microsoft Edge > Allows you to configure the Enterprise Site List" did work for me.
2. Group policy & Intranet Site
   The article said to use "Administrative Templates > Windows Components > Microsoft Edge > Send all intranet traffic over to Internet Explorer" which did not work
   UNLESS you also go into "Internet Explorer > Tools > Options > Security > Local intranet > Sites > Advanced" and then add the site to the list.
   The article is assuming that the user knew to do this step!

Here is the registry keys just in case someone wants to do all this without opening group policy / IE options.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main]
"SendIntranetTraffictoInternetExplorer"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Policies\Microsoft\MicrosoftEdge\Main]
"SendIntranetTraffictoInternetExplorer"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\google.com\www]
