Can't be done. You can request a Read Receipt but that's about it.

Does anyone have any suggestions on how to receive reply message
automatically when the receiver opens the email I sent? How to set this
option in Outlook Express? so whenever I send email to someone, they will
send me back a received message by opening the email.
Thanks in advance for any suggestions
