A

Active Messaging collection: An object that contains zero or more Active Messaging objects of the same type. The Active Messaging Library supports two types of collections: large collections and small collections. With large collections, you can use the object's methods to get the first, next, last, and previous items within the collection. With small collections, you can access all items in the collection using an implied index.
Active Messaging Library: An OLE Automation programming interface that is a component of the MAPI client interface and is used primarily by Visual Basic and Visual C and C++ client application developers. The Active Messaging Library furnishes programmable objects, like Microsoft Excel objects and Microsoft Access objects, that make available properties and methods that can then be managed by Visual Basic (VB) and Visual Basic for Applications (VBA) programs. It provides a layer between the client application and the MAPI client interface component. See also Simple MAPI, Common Messaging Calls.
Active Messaging object: An object contained in the Active Messaging Library, such as a session object, folder object, or message object, that exposes properties and methods. See the Active Messaging Library documentation in the MAPI SDK.
address book: A MAPI object that manages a collection of one or more types of recipient available to a client application. A recipient can be a messaging user or a distribution list. The recipients are stored in address book containers that are organized hierarchically. At a given workstation an address book includes recipients from every address book container furnished by every address book provider in the current profile. Address books implement the IAddrBook : IMAPIProp interface.
address book container: A MAPI object that contains recipient information furnished by an address book provider. Address book containers implement the IABContainer : IMAPIContainer interface.
address book provider: A MAPI service provider object that manages zero or more address book containers, enabling users to address messages and create recipients. An address book provider can furnish containers or templates or both. A fax address book provider, for example, typically furnishes messaging user and distribution list templates but no containers. Address book providers implement the IABContainer : IMAPIContainer, IABLogon : IUnknown, IABProvider : IUnknown, IDistList : IMAPIContainer, and IMailUser : IMAPIProp interfaces. See also address book container, container, message, template. For more information, see Developing an Address Book Provider.
address properties: A fundamental set of five properties for every recipient that describes the recipient's e-mail address and address type, display name, entry identifier, and search key. For more information, see Base Address Properties.
advise sink: A MAPI object that registers for and receives notifications of specific events in other objects. The notification of an event is asynchronous to the event itself, that is, it is communicated at an indeterminate time following the event, and the object generating the event does not wait for any response to the notification. An advise sink provides a callback function for events that occur in a message store, address book, or session. Advise sinks implement the IMAPIAdviseSink : IUnknown interface.
ambiguous name resolution: (ANR) See name resolution.
application form library: A form library that supplies forms to a particular workstation. Forms installed in an application form library are available to every MAPI client application on that workstation, regardless of what message store or profile is currently active. See also folder form library, personal form library.
ASN: (Abstract Syntax Notation) An ISO standard for encoding of human-readable symbols, such as header tags, into condensed binary form. ASN.1 corresponds to CCITT standards X.208 (for the notation) and X.209 (for the encoding rules). In turn it forms part of the specifications for the X.400 and X.500 series of standards, as well as for various other specifications.
associated contents table: A table of information associated with a folder and normally stored in the "hidden" or associated part of that folder. It typically contains forms that are installed into the folder and view descriptors that are associated with the folder. See also associated information, contents table, form, standard contents table, view descriptor.
associated information: Additional information kept in a folder with a specific purpose for a client application, such as a view or a form definition. Associated information is typically not visible to the user. See also associated contents table.
attachment: A MAPI object that contains additional data, such as a file or OLE object, associated with a message. Attachments implement the IAttach : IMAPIProp interface.
attachment table: A MAPI table object that provides access to information about a message's attachments. Each row represents a message attachment.
