Hi @Josh Matthews ,
I was hoping we could somehow get our site added to Microsoft's list to avoid clients having to do anything.
Unfortunately, you cannot add your site to the Microsoft's list.
If this is not possible and you have any other suggestions I would be extremely grateful.
Edge IE mode was originally designed for enterprise users. Enterprise users must join the client to the domain to realize the deployment of IE mode. So what you can do in your case is to install and modify the registry to achieve this requirement, otherwise I'm afraid there is no other viable option.
Regards,
