If you attempt to address a new message from your Contacts, you may receive the following error message:

The address list could not be displayed. The Contacts folder associated with this address list could not be opened; it may have been moved or deleted, or you do not have permissions. For information on how to remove this folder from the Outlook Address Book, see Microsoft Outlook Help.

This behavior can occur if the Microsoft Outlook Address Book setup is damaged.
