Hi there,I have a root domain where I installed Exchange 2007. Afterwards I added aanother domain in the same forest, where I intend to create my user accounts. In theotherdomaindomain, I ran a setup /PrepareDomain as per MS instructions for each domain where you intend to have mail-enabled recipients.In the Exchange console, the server is using DCs and GCs in both domains.However, when I try to create a new user, I only see the root domain node, no sign of the new domain I have created in the "Organizational Unit" field.How can I create a mailbox for a user in my new domain?Thanks.

Did you try after changing recipient scope to another domain? How to Change the Recipient Scope http://technet.microsoft.com/en-us/library/bb124791.aspxAmit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com

That was exactly it, thanks a lot! At least I did the rest of the preparation correctly ;o)
