I have a machine here running Windows XP with office 2007. The prob is when you send a mail it shows 2 mails leaving outbox. I've checked for spyware with ScanSpyware and the have licensed nod32 firewall and antivirus running for over a year. I checked if it might be some setting but everything is seems fine. No read receipts etc. which I thought could cause it either.

Has anyone ever heard about outlook 2007 or earlier doing this? It bugs me and would really want to change this, or atleast understand why.
