Hopefully this is a dumb question, but I have installed exchange 2007 and need to create the user mailboxes as they were not created during install, Ihave no exchange tabs in AD like with 2003 is that right? and the wizard in exchange manager only allows me to craete 1 mailbox at a time, how do i create mailboxes for several users in one go?

Check out this article it should help. http://techstarts.blogspot.com/2007/02/bulk-user-creation-using-powershell.html

Hi, thanks for that, unfortunately I may have misled you slightly I already have the users its the mailboxes I need to create.

You'll need to use the Exchange Management Shell to do this. A lot of it depends on how you want to do this,i.e. are the user accounts all in the same OU, or do they are share a common Active Directory attribute such as their 'department' attribute? Bharat Suneja has an excellent post on how to do this here: http://exchangepedia.com/blog/2006/12/bulk-mailbox-enabling-users-exchange-shell.html
