No modifications are permitted to messages in the Inbox, except for message deletion. Therefore, all properties on an Attachment object are treated as read-only when the grandparent Message object is in the Inbox. When the access is described as read/write in the following table, that access applies only to attachments on messages in the Outbox.

An attachment is an object, such as a file or another object, that is associated with and transmitted with a Message object. The Attachment object does not specify its location within the message. The client application makes all the display decisions for a message, including whether its attachments are to be displayed, and if so, when and where.
The CDO for NTS Library does not manage the actual display of the attachment. The properties of the Attachment object simply provide information that the displaying application can use to find and open the attachment, and to convert its contents into a display.
