Default Message Stores

A default message store is one that client applications can use for general purpose messaging tasks. There are a number of optional features for message store providers that become required if the message store provider is to be used as the default message store. They are:

• Implementing the special folders: Inbox, Outbox, and search-results folder.
• Providing read and nonread reports.
• Allowing incoming and outgoing message submissions.
• Allowing creation of messages with arbitrary message classes.
• Supporting named and multivalued properties.
• Supporting the IMSProvider::SpoolerLogon method, even if the message store provider is tightly coupled with a transport provider.
• Supporting associated contents tables.
• Supporting notification of the MAPI spooler when there are messages in the outgoing message queue.
