18 - Working with Recipients and Address Lists

Abstract

This chapter provides an overview of the key Outlook objects that represent information about recipients and address lists. The Namespace.GetSharedDefaultFolder method requires a Recipient object as one of the parameters necessary to return a folder from another user's Exchange mailbox. This method provides an easy way to create a Recipient that is not attached to any message or other Outlook item. The Recipient object is also crucial in determining whether a user is available for a meeting at a particular time. The most basic address-related object is the AddressEntry. The ExchangeUser and the ExchangeDistributionList objects inherit the properties and methods from the AddressEntry object. If a user has an Exchange mailbox, one or more address lists related to the Exchange server will be present. The Exchange Global Address List is likely to contain the maximum information about each entry. All AddressList properties are read-only. The only technique in the Outlook object model related to showing or hiding an address list is the ability to display any Outlook contacts folder as an address list under the Outlook Address Book.
