Last modified: July 23, 2011

Applies to: Outlook

Contains a table of restrictions that can be applied to a contents table to find all messages that contain recipient subobjects that meet the restrictions.

General messaging

This property can be excluded in IMAPIProp::CopyTo operations or included in IMAPIProp::CopyProps operations. As a property of type PT_OBJECT, it cannot be successfully retrieved by the IMAPIProp::GetProps method. Its contents should be accessed by the IMAPIProp::OpenProperty method, requesting the IID_IMAPITable interface identifier. Service providers must report it to the IMAPIProp::GetPropList method if it is set, but may optionally report it or not if it is not set.

To retrieve table contents, a client application should call the IMessage::GetRecipientTable method.

This property can be used for subobject restriction by specifying it in the SSubRestriction structure. This enables a client to limit the view of a container to messages with recipients meeting given criteria. A message qualifies for viewing if at least one row in its recipient table, that is, one recipient satisfies the subobject restriction.

Note  Using subobject restriction results is the equivalent of an IMAPISession::OpenEntry call on every message in the table. Depending on the client application and the number of messages to be searched, it can affect performance.

The PR_MESSAGE_ATTACHMENTS (PidTagMessageAttachments) property and this property are similar in usage. Several MAPI properties provide access to tables:



PR_CONTAINER_CONTENTS (PidTagContainerContents)

Contents table

PR_CONTAINER_HIERARCHY (PidTagContainerHierarchy)

Hierarchy table

PR_FOLDER_ASSOCIATED_CONTENTS (PidTagFolderAssociatedContents)

Associated contents table

PR_MESSAGE_ATTACHMENTS (PidTagMessageAttachments)

Attachment table


Recipient table
