About the Store API
Published: July 16, 2012
The Store API provides miscellaneous store functionality to store providers. It provides the following defintions, data types, properties, and interfaces.
Store providers that do not require any of the functionality offered by these named properties can simply ignore them and not implement support in the IMAPIProp interface. Because these properties are provided starting in Microsoft Outlook 2003 Service Pack 1, adding them to a store in an earlier version of Microsoft Outlook has no effect. They are ignored if they do not exist or if their value is false.
The MAPI Protocol Handler checks the Windows registry for stores that it should index for search purposes. Store providers that want to be indexed must be registered in the Windows registry. For more information about registering store providers for indexing in Outlook 2013 or Outlook 2010, see About Registering Stores for Indexing.
MAPI store providers can choose to allow the MAPI Protocol Handler to crawl and index messages in the store, or send notifications to the indexer only when there are messages to be indexed. For more information about notifications-based indexing, see About Notification-Based Store Indexing.
