We have two women in our company who have recently gotten married so naturally their last names have changed. I've been able to update their Active Directory account with the new names and created new email addresses to reflect the name change as well. The problem I'm having is that when I set the new email address as the primary address it doesn't stay that way. After a few minutes it reverts back to the old address. I want the new address to be the primary so that when they email people it shows coming from the new name instead of the old name. When you go into Outlook the mailbox has their old name on it as well. What could be causing the active directory account to revert back to the old email address. I don't want to delete the old email address yet because people might still be sending emails to the old address. We're running Windows Server 2003 R2 Standard with Exchange 2003. All service packs are current. Thanks in advance for any help.
