Hi, I havea forest with two child domains. My Exchange server 2003, is installed only on the root domain. When i create a user in a child domain, refering the exchange server name, and the mailbox store, the mailbox is not created on the Exchange Server. This is a supported configuration ? Regards David

Hi David, This is a supported and common configuration. Does the account creating the mailbox-enabled users have the proper rights within the top-level forest where the Exchange server resides? Chris
