SUMMARY
In the Microsoft Mail Software Development Kit (SDK) for HyperCard,
the following function removes the enclosure, specified by the value
of "index", from the message in "messageRef":
msmail(removeEnclosure, messageRef, index)
If index has a value of negative one (-1), all enclosures are removed.
This call should be used only for messages that have not yet been
sent. Removing an enclosure from a sent message will not remove the
enclosure from the server.
For example, to forward a message, but not the enclosures, use the
following commands:
put msmail (getMessage, messageType, messageID) into messageRef
put msmail (createForward, messageRef) into forwardMessage
get msmail (removeEnclosure, forwardMessage, -1)

Documentation."
