I have installed a brand new Exchange 2007 SP1 in our Active Directory. Before Exchange was implemented, Active Directory had the default email address for each user as janedoe@companyname.com. This email is being hosted by a non-Exchange server. Thenew default email addressin Exchange 2007 is janedoe@dept.companyname.com. When I create a new mailbox, it automatically gets the new Exchange default email address. How can this be updated in Active Directory as the new default address? Any help is appreciated!
