The IMessage COM Interface

The CDO IMessage interface defines a set of methods and properties that encompass the most common messaging functionality. COM classes that expose implementations of the IMessage interface communicate to clients that they support the creation and management of messages in RFC 822 format. Objects exposing this interface can be used to:

• Send messages and respond to existing messages.
• Manage message recipients.
• Manipulate the message's content in both plain text and Hypertext Markup Language (HTML) formats.
• Manage attachments.
• Create MIME Encapsulation of Aggregate HTML Documents (MHTML) formatted messages.
• Set the configuration settings used for the object.
• Respond to the message.

In CDO for Windows 2000, only the Message COM class exposes the IMessage interface.
