How to cancel sending of read receipt in Outlook

I have agreed to send a read receipt to e-mail I received, but my Outlook
2003 gave me following error message:

Task 'pop.gmail.com - Sending' reported error (0x800CCC0F) : 'The connection
to the server was interrupted. If this problem continues, contact your
server administrator or Internet service provider (ISP). The server
responded: 421 4.4.5 Try again later, closing connection.'

I am still sending and receiving e-mails, but every minute I receive the
above message, because my Outlook can not send that read receipt. Now I want
to cancel sending of the read receipt, but it is not in my "outbox" folder
and I can not delete it - how can I stop my Outlook from trying to send that
read receipt?

Maybe this will help http://www.outlook-tips.net/hoÂ*wto/delete_rr.htm
