Symantec Enterprise Vault 10 Icons and functionality are not available over OWA for mailboxes located on remote mail servers

Symantec Enterprise Vault 10 Icons and functionality are not available over OWA for mailboxes located on remote mail servers.

I do not have the issue with the Main Campus.

I cannot say if this has ever worked on the remote sites as no one has complained.

Environment:

Exchange Server 2010 (14.03.0174.001) on Windows 2008 R2

Enterprise Vault version 10 Windows 2008 R2)

OWA 2010 Extensions version 10.0.4.1333 (on all CAS role servers (6))

Main campus has a 3 CAS server array and 2 Mailbox server

Remote sites (3) running CAS and Mailbox roles

I have searched and see a lot of information on this topic, but have not been able to resolve this.

Any (good) help is tremendously appreciated.
