EV OWA archive explorer/search prompt for credentials

[James_Drake]

EV 10.0.4R1 with Exchange 2010 SP3 RU5 - single server in both cases.

Testing EV integration with OWA internally.

Customer AD domain is customer.local. Exchange 2010 has been setup to present all CAS, ECP etc.. URL's with customer.co.uk, internal and external fields. Split DNS is used to present hosts in the customer.co.uk zone with internal IP addresses to internal users.

Using server.customer.co.uk internally. OWA loads ok. EV shortcuts are double-clicked and the content is presented seamlessly.

If I click archive explorer or search in the OWA panel I get prompted for credentials. Entering them allows the use of those functions. I want it to be seamless so there is no second credential prompt. I have gone over and over the OWA installation and configuration guides and turned on OWA logging for EV. I cannot seem to see what is wrong, although at the back of my mind I think I have had this before but cannot recall what the solution is.

take OWA out of the equation for a moment. if you browse to http://evserver/EnterpriseVault/ArchiveExplorerUI.asp or http://evserver/EnterpriseVault/Search.asp what happens?

[James_Drake]

It just goes straight into the explorer or search without prompting.

[AndrewB]

can you enable logging in OWA, try to access AE and Search and then post it here?

What if you go to http://evserver.fullyqualified.local/enterprisevault/archiveexplorerui.asp? Sounds like IE might not be allowing an automatic logon for that address, and the fully qualified name needs adding to the intranet zone.
