The PST Override Handler Interface Identifiers might not be defined in the downloadable header file you currently have, in which case you will find them in the MAPI Constants topic, and can copy and add them to your code. Use the DEFINE_GUID macro defined in the Microsoft Windows Software Development Kit (SDK) header file guiddef.h to associate globally unique identifier (GUID) symbolic names with their values.
