Windows

I'm just learning how to administer and deploy MS Exchange 2003 but I'm pretty much knowledgeable on WIN2K and 2003 administration and Active Directory. I need to know the step by step creation of resources in MS Exchange for purposes of scheduling and managing conference rooms and other resources.

I was told to create a user in Active Directory Users and Computers and mark the Create an Exchange Mailbox. But I still can't complete the process and be able to make it available in my Address List.
