The PR_PROVIDER_UID property is computed by all service providers. It contains a MAPIUID structure associated with, and usually hard-coded by, the provider. It is typically used by a client application that is interested in only the address book containers supplied by a particular provider.
PR_PROVIDER_UID appears only as a column entry in the provider table.
