Introduction
When Microsoft Outlook is connected to a Microsoft Exchange Server the default list of addresses list displayed by the Outlook Address Book will refer to the Global Address List in exchange for your organisation. In most cases you will want to change this option so that by default your Microsoft Outlook Contacts will be displayed whenever you are selecting recipients for an email. The instructions below explain how to change your Address Book Options in either Microsoft Outlook 2007 or Microsoft Outlook 2010.
