 [0x8007203a] 

The error code 0x8007203a translates to “The server is not operational.” DTrace logs showed that the EV server was unable to perform LDAP queries via the Global Catalog (GC) because it could not connect to port 3268 on the domain controller.

NOTE: This port is critical for directory lookups in Active Directory, especially when locating Exchange server objects during the archiving process.

To test the Global Catalog (GC) connectivity on port 3268, use the following PowerShell command:

Test-NetConnection -ComputerName -Port 3268

 The network firewall or security policies must permit TCP traffic on port 3268 between the Enterprise Vault (EV) server and the Domain Controllers to ensure proper communication with the Global Catalog.
