Issue



Enterprise Vault (EV) Archive Explorer and Integrated Search in Outlook Web Access (OWA) 2007 does not work externally via Internet Security Accelerator (ISA) 2006

Archive Explorer and Integrated Search point to internal Enterprise Vault (EV) server name while accessed externally via OWA 2007 where OWA URL is same for external and internal web access


Error



IIS error code 404 not found on client.


Environment



Enterprise Vault (EV) 9.0.1 and Exchange Server 2007.

Internet Security Accelerator (ISA) 2006 Server


Cause



In the ISA rules, rule for OWA access configured to route external client IP addresses to Client Access Server (CAS)


Solution



This change will modify the OWA rule to mask the client IP Address by sending the ISA Server's IP Address to the Client Access Server, if this is not a desired change then the 'EnterpriseVault_ExternalIPAddresses' option should not be used

1. Login to the Internet Security Accelerator (ISA) 2006 Server using administrative privileged account.
2. Go to the Rules section and properties of the OWA 2007 Rule.

4. Save and apply the rule changes.
5. On the Client Access Server (CAS), add the 'EnterpriseVault_ExternalIPAddresses' application setting using the methods described in the Web.config options for Microsoft Exchange 2007 Outlook Web Access (OWA) document:
