EV OWA not functioning

Hi All,

Exchange 2010 and EV 10, 2 CAS Servers and 4 MBX. I have installed the EV OWA extensions on both the CAS Servers. And ran owausers.wsf script in order to create EvAnon directory on vault server. Everything went fine.

But when I logged into OWA from one CAS server I cant access EV functions, where other work just fine. Searched online KB, enabled logging for extensions in web config file. I accessed owa again and checked the log folder for any logs created, but there are none.

Any idea?
