2.2.1 Search Folder Definition Message

A search folder definition message is stored as an FAI message, as described in [MS-OXCMSG] section 1.3.2, in the FAI contents table, as specified in [MS-OXCFOLD] section 3.1.1.2, of the Common Views folder, as specified in [MS-OXOSFLD] section 2.2.1, within a message store. A search folder definition message is used to persist a search folder within a mailbox, thereby enabling the client to maintain the user's search folders across multiple machines and reliably re-create them if needed. A search folder ceases to exist if its search folder definition message is deleted. For more details about how a search folder definition message relates to a search folder and a search folder container, see section 2.2.4.
