EV Outlook addin error

Hi Everyone,

Need an urgent help help on an issue with Enterprise vault app.

Customer has implemented EV 11.0 with Outlook 2013 on windows 2012. IE Version 11.

He has one external domain and one internal domain.

In internal domain he has created a dns alias name for the ev server mapped to the hostname of the server so that in future if he wants to add another server he can do that.

We created a certificate with name of external domain and kept the Subject Alternative Name as the name of the ev server in internal domain.

As of now everything is working fine except when we try to open the Enterprise vault add in for Outlook it is showing an error "Page cannot be displayed" in it.    

As well when we try to open the below mentioned url's in IE it throws Java script errors : 

https://appsforoffice.microsoft.com/lib/1.0/hosted/office.js ■ https://ajax.aspnetcdn.com/ajax/3.5/MicrosoftAjax.js 

- Tried to check Fidler Trace, however unable to capture the Http Traffic

Please suggest we need urgent help in this.

 

Regards,

Expecting a response.
