You can do this in the GUI under Recipient Configuration > New Mailbox > User Mailbox > Existing User, and choose the user you wish to create the mailbox for.
From the shell:
You must be logged in with an account with sufficient privilege to create a mailbox in Exchange.
As an aside, there have been reported issues with the built-in Domain Administrator account and Exchange 2010. If you experience any issues with the built-in account, create a new account with administrative privilege.
You can create mailbox in Exchange using Powershell command or using Exchange Management Console (EMC). But, Process is little bit long using EMC. Go though this Microsoft help section > technet.microsoft.com/en-us/library/aa998319(v=exchg.141).aspx
