Just had to change a user account name in Active Directory due to a user getting married. All pretty straightforward, however after several hours, the change hadn’t appeared in the global address list in Outlook, so I thought I’d look into it.
Here are the steps necessary to prompt the change to happen sooner:
1) In Exchange System Manager, go to the offline address list, right click and select Rebuild
2) In Outlook – go to send/receive and select Download Address Book
You should now see the new name appear in the contact list.
