Hi @YuZhou-MSFT

I am having the same issue as well. I saw this MS Docs article where Prerequisites section mentioned Windows Server 2016 as being applicable to Edge with IE mode. Is this something else?

Hi @YuZhou-MSFT .

I have followed the instructions for the configure by group policies and was wondering if this would be the correct site list values if i want my site to be opened in MSEdge in IE 11 mode? I don't seem to see the IE mode icon when browsing to the url site (not being rendered in IE 11 mode).

 <site url="[servername]:10035">
     <compat-mode>IE11</compat-mode>
     <open-in>MSEdge</open-in>
 </site>

For testing purposes, I tried this one and that opened in IE so it confirms that it is able to see my sites xml file.
<site url="[servername]:10035">
<compat-mode>IE8Enterprise</compat-mode>
<open-in>IE11</open-in>
</site>

Thank you for your help!
