All, We are going through a migration to Exchange 2010 and am looking for a powershell script that would create a mailbox for every user who belonged to a specific OU. I've found some which ask for the username manually and will set the rest of the attributes, but is there something that will read the user objects from an OU and create the mailbox with some settable attributes? Thanks!

Lots out there. You can filter on OU if desired. Modify the scripts as required.

Many thanks!!

This would mailbox enable every user in the "finance" OU: Get-User -OrganizationalUnit contoso.com/finance | Enable-Mailbox If that's not what you need can you provide more details? What attributes do you need to set? Where would the values come from?
