Remarks
GUID structures are used in MAPI as follows:
- In the MAPIUID structures that uniquely identify service providers.
- For interface identifiers.
- In the property set names of named properties.
Message store and address book providers call the Microsoft utility UUIDGEN.EXE to generate a GUID structure to use in their MAPIUID structure.
