2.2.5.1 PidNameExchDatabaseSchema

DAV property name: urn:schemas-microsoft-com:exch-data:baseschema

Data type: PtypMultipleString ([MS-OXCDATA] section 2.11.1)

The PidNameExchDatabaseSchema property ([MS-OXPROPS] section 2.425) gets or sets an array of URLs identifying other Folder objects within the same message store that contain schema definition items.

The PidNameExchDatabaseSchema property SHOULD be used in conjunction with the PidNameExchDataSchemaCollectionReference property ([MS-OXPROPS] section 2.427) to define a Folder object's schema scope. Set this property on any Folder object containing schema definition items to identify subsequent Folder objects to search for schema items. Clients and servers SHOULD always check the current Folder object before proceeding to the Folder objects identified by the PidNameExchDatabaseSchema property.

The order in which the URLs are listed in this property is significant. When searching for schema definition items, applications perform a breadth-first search for definition items within the Folder object's schema scope starting in the Folder objects identified by the schema-collection-ref property. Folder objects subsequently identified by the PidNameExchDatabaseSchema property of this schema collection Folder object are then searched in the order that they appear in the property. During the search, the first encountered definition item is always used, and other subsequent definition items are ignored. Each PidNameExchDatabaseSchema Folder object can then in turn define its own set of PidNameExchDatabaseSchema Folder objects. These Folder objects are searched in the order that they appear in the property.
