This policy setting allows you to specify what occurs when a program attempts to gain access to a recipient field, such as the “To” field, using Simple MAPI. If you enable this policy setting, you can choose whether Outlook always allows access to the recipient field, always disallows access to the recipient field, or prompt users to specify whether to allow or disallow access to the recipient field. If you disable or do not configure this policy setting, Outlook prompts users to specify whether to allow or disallow access to the Address Book.
