Hi,
We have installed Exchange 2010 EV extensions on our CAS server for OWA. Internally on the LAN, Ent Vault works fine when redirecting directly to the EV server URL.
I have configured the CAS server with EnterpriseVault_ExternalIPAddresses to force the the use of the external OWA domain name/external URL when using OWA from an external source. I have configured IIS ARR as a reverse proxy in the DMZ, just to pass through to the CAS server only on port 443.
When I access an archived email using OWA externally, the email does load. However, when I select Archive explorer or Search Vault, I am getting error 404. I am unsure if I need further configuration on the IIS ARR server, or if it is something I am missing regarding EV? As the CAS server should be proxying EV, I thought that configuring ARR just for port 443 to the CAS server was correct? The EV server is only using port 80 on the LAN for connectivity, could it be this that is stopping the CAS from proxying correctly?
Thanks in advance.
