2.2.2 Search Folder Container
Although the search folder definition message persists, a search folder container only exists if the search folder (2) is an active search folder. If a search folder (2) is inactive, the search folder container will not exist. For more details about active and inactive search folders, and the relationship between search folder definition messages and search folder containers, see section 2.2.4.
A search folder container is created and modified as described in sections 220.127.116.11 and 18.104.22.168. A search folder container uses search criteria, a feature that is not unique to this protocol. These folders also require the use of several common properties.
