If PDF is properly associated with Adobe Reader (or Acrobat) then you should still be able to double click the attachment and it would open in that application. You can then save it and do what you want with it. It's been a long time since I used Outlook 2003, but I don't recall it being different? Nor do I see how your proposed process is going to make any difference. If you double click the attachment, it is the attachment embedded in the message that's opening not the one you have saved to the hard drive. It would appear that your process simply duplicates the original message. That is possible of course, but I don't see where it helps?
