If you're having issues with your Outlook address book, such as a new employee's information not showing up, there may be a simple solution. This article shows how to manually update the Global Address List (GAL) in Outlook (version 2010 and above).
The Global Address List is a directory of contact information that is stored in a central place called the Exchange Server. As a faculty/staff member, your Outlook program automatically syncs with the Exchange server on a regular basis.
But issues can occur with the syncing. For example, say a new person joins your workgroup. You are unable to see his information in your address book. It may be that the information from the Exchange server has not yet flowed to your local Outlook program. So to force your Outlook to sync with the Exchange server you can manually update the GAL.
To manually update the GAL, do the following:
Click Download Address Address Book.
The Offline Address Book dialog box appears.
