MAPI Properties

MAPI Property: PR_MDB_PROVIDER
Description: Contains a provider-defined MAPIUID structure that indicates the type of the message store.
Property ID: $3414
Property type: PT_BINARY
Area: ID properties

Remarks:
The MAPIUID structure identifies the type of message store. The value is computed by message store providers on message store objects and is unique to each provider. It is typically used for browsing through the message store table to find a store of the desired type, such as public folders.

This property is analogous to the PR_AB_PROVIDER_ID (PidTagAbProviderId) property for address books.
