14 - Using PropertyAccessor and StorageItem

Abstract

There are two key new objects added to the Outlook object model: (1) the PropertyAccessor object, which provides access to the hidden properties of items, folders, attachments, and address entries, (2) and the storageItem object, which provides access to the hidden items that contain settings such as folder archive options. Much of the work with StorageItem objects involves the usage of Property-Accessor to access the properties of a hidden item. Developers can create their own properties and, in certain folders, their own storage items to hold information specific to their applications. The PropertyAccessor.SetProperty and setProperties methods simplify the operation of setting property values by creating any properties that do not already exist. All the PropertyAccessor methods take a SchemaName or SchemaNames parameter. A custom property created with the UserProperties.Add method is visible to the Outlook users. A property created with the PropertyAccessor.SetProperty is hidden from users.
