I'm configuring an Exchange 2010 server. I have the proper email address setup so that when a mailbox is created for an existing active directory user the email address is automatically formatted the way we want. firstname.lastname@example.org.
Unfortunetly when I create the mail boxes the default short name is firstnamelastname. I would like the default short name to be firstname.lastname.
Is there a way to do this? I want to create 150 accounts all at once.
