MIM 2016 SP1 Portal POP-UP UI Does Not Work

Hi Everyone,

We upgraded our environment from FIM 2010 R2 to MIM 2016 SP1 last week. After upgrade we notice that Pop URL for any object is not working as the way it was working in FIM2010 R2 version.

Below are the URL format which we were using in FIM 2010 R2 version to open group object type in pop windows:

In FIM 2010 R2:-

https://localhost/identitymanagement/aspx/customized/EditCustomizedObject.aspx?id=6978f402-6efd-4910-9de6-25d5f2fda843&type=Group&_p=1

However, when we remove "&_p=1" and try the rest of URL in MIM then object open but not in pop windows. 

Anyone knows what's URL we should use in MIM 2016 SP1 version to open any object in pop window.

Thanks in advance!!
