Important: You cannot edit Address Book entries from within the Address Book. You make changes by changing the information for the individual contacts in your Outlook Contacts. After saving the contact, the changes for that entry will be updated in the Address Book.
Think of the Address Book as a "container" of all your contacts. You can view them there, and add them to messages, but you add and update the information from within Outlook Contacts.
Note: By default, the Outlook Address Book contains all the Contacts in your main Outlook Contacts folder. If your organization has a Global Address List (GAL), these contacts are also included. If you have created any additional contacts folders, these can also be included.
New contacts are created using the contact form, an Electronic Business Card, or by adding a person's name, e-mail address, or Electronic Business Card by saving them to your Contacts when received in e-mail messages. After they are saved, the changes appear in the Address Book.
