Outlook 2003 cannot show user properties in the Unread Mail. I am hoping Outlook 2010 can.
I am hoping that Outlook 2010 has some native feature that integrates this functionality.
500 points to anybody who can guarantee that the answer is yes.
P.S. I am not a rookie on this subject so please don't bother explaining how to use the Field Chooser wizard. It is not a matter of opinion, it is just a fact that native Outlook 2003 doesn't allow user defined fields to appear in the unread mail folder.
But, I have developed a workaround for 2003, but it is less than ideal: The user selects a group of emails and runs my ShowProperties vba macro which displays a vba form with subject and user properties.
