Exchange maintains two primary address books. The Global Address Book is a listing all of mailbox users and message storage containers maintained on the SPU Exchange Server. This is usually the "default" directory used in Outlook 2003/2007 or in Webmail when you want to check an email address.

If you have stored Personal Addresses in Webmail or Outlook, they are stored in your Contacts folder.

Modify Secondary Address Books:

The default Address Book, plus any secondary address books can be modified within Outlook 2003/2007. To do so, take a look at the following steps:

1. In the main Outlook window (as opposed to in a new message), go to the Tools menu.
2. Select E-mail Accounts
3. Select View or change existing directories or address books and click Next .
4. To make your contacts show up in the Outlook Address Book, select Additional Address Books. Hit Next
5. Select Outlook Address Book. Click Next. Then OK.
6. Close and restart Outlook.

Directory Display Preferences:

Your listing in the Exchange Global Address Book is controlled through the Banner Information System. Log in to Banner, select Directory Preferences, and you can modify some of the fields that are made visible in the Global Address Book.

New Contact not in Global Address Book:

If a New Contact isn't appearing in Outlook, but resolves in Webmail (you can log into Webmail and send a message to that person) then the culprit is the Offline Address Book in Outlook. You can manually update the Address Book or wait till the next day (it updates every 24 hours).

By default, this Address book updates at 4:00 a.m.

To update it manually:

1. go to Tools -> Send/Receive -> Download Address Book...
2. Uncheck Download Changes since last Send/Receive
3. Make sure Download Full Details is checked
4. Click OK, wait for the download to complete (This may take some time)
5. Check if user appears in Global Address List.
