Attachment Associate an additional object with a message. Folder Open the default Inbox or Outbox folder in a message store. Message Compose, populate, send, and receive an e-mail document. NewMail Send a message without having to log on to a session. Recipient Specify information for a messaging user intended to receive a message.

The Session object uses the LogonSMTP method to differentiate the access from the Logon method of the the CDO Library, which interfaces with Microsoft Exchange Server. The SMTP server component of IIS has its own message store mechanism. The Inbox and Outbox are mapped to directories in the file system, and no other folders exist. Message transfer takes place in such a way that spooling appears instantaneous, so the Inbox has no incoming queue and the Outbox is always empty. When CDO for NTS is running with IIS, the Inbox is a single common folder shared by all SMTP recipients and applications.
