How to delete Hidden Message in the Outlook Outbox

[kmulder]

I use Outlook XP at work to READ me private mail. My ISP can not handle smtp (sending) with the ip-address I have at work. So I block the e-mail profile to not SEND message.
Yet, I got a message in my private mail with a Read Receipt request and Outlook now tries to send this message to my ISP, without any luck.

How can I delete this HIDDEN message in my Outbox? It is in there, but since it is a Read Receipt, it is not visible.

Hope someone can help.
Regards,

KM

well you can try to set the options to not send a read response. Under tools->options->email options->tracking options. that may purge the read reponse email

You could try using the mailbox cleanup option
