Cause

  1. Closest GC (Global Catalog) registry key implemented:
Reg Key Location: HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider.
  1. ​GC was hardcoded in Vault Admin Console.

Solution

Remove:

  1. Improperly configured Closest GC Key value:
    Key Location Settings
    Closest GC
    HKEY_CURRENT_USER
    \Software
      \Microsoft 
        \Exchange
          \Exchange Provider              
    Value name: Closest GC
     
    Data type: REG_DWORD
     
    Radix: Hexadecimal  Value data: 0x00000001
  2. Hardcoded GC from Vault Admin Console.
Note:  A specific Global Catalog can be specified on the domain properties in the Vault Administration Console:
 
Add:
  1. DS Server registry key value of the Fully Qualified Domain Name FQDN of CAS Array
    Key Location Settings

    DS Server

    HKEY_CURRENT_USER
    \Software
      \Microsoft 
        \Exchange
          \Exchange Provider        
    Value name: DS Server
     
    Data type: REG_SZ (string)
     
    Value data: FQDN of the CAS
    server
