MAPI Properties

This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

This section contains canonical properties that are supported by the Outlook 2007 Messaging application programming interface (API). Each canonical property corresponds to one or multiple related MAPI properties. For more information on canonical properties, see MAPI Canonical Properties. For a general explanation of how MAPI works with properties and a list of the properties available for each object, see MAPI Property Overview. For information about the property-related macros, see the reference page for the SPropValue structure. For a comprehensive list of MAPI properties and their mappings to canonical property names, see Mapping Canonical Property Names to MAPI Names.

Note: Unlike members of OLE variant arrays, every member in a MAPI multivalued property array is of the same type.
