Data type:


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 can optionally report it or not if it is not set.

To retrieve table contents, a client application should call the IMAPIContainer::GetContentsTable method. For more information, see Contents Tables.

This property, PR_CONTAINER_HIERARCHY (PidTagContainerHierarchy) , and PR_FOLDER_ASSOCIATED_CONTENTS (PidTagFolderAssociatedContents) are similar in usage. Several MAPI properties provide access to tables:
