At the moment we have our exchange infrastructure distributed geographically across 3 main regions eg. Americas, EMEA, Asia. AD is a single domain with multiple sites based on georgraphic location. We have EV sites in each region, each configured independtly of the other sites. The scenario is that we have a user (User A) who is in the Asia region, trying to access an email item from the archive of a former employee (User B) from our Americas region, whose mailbox and archive reside in the Americas site. User A has full access to User B's mailbox in exchange and full access to User B's EV archive. However, when trying to open an archived item, the user is prompted for credentials. The credential prompt seems to be asking to log on to our Asia EV site, instead of the Americas site (which is what I expected, since the target mail item resides on the vault in the Americas site).
I've followed the instructions on this thread: https://www-secure.symantec.com/connect/forums/access-archives-different-enterprise-vault-site
however I continue to experience the same issue. Can anyone else offer any suggestions?
