Hi Andonia,
You could do this on the Exchange server if you have access to the development platform. That would be a solution for the entire org, but would require a small amount of code.
If you're looking for a solution for a standalone laptop that has both Outlook and InfoPath installed, I recommend using a VBA macro that launches. We've done this before to automatically create InfoPath forms from email. We have the code and can share it with you but will need to charge an hour of consulting time to describe what it does. It's ~20 lines of code. Try Google'ing VBA Outlook macros and you could probably spend 1-2 hours investigating, or you could just send us a small donation. We don't have time to spend an hour responding to every post since we have to keep the business profitable too... thanks for your understanding.
Send me email if you need help,
