I finally have something that works well. This macro will save attachments on arrival to the drive of your choice. The attachment is saved using a guid so there is no conflicts.
I utilized the Outlook Object model and the AdvancedSearch object.
One interesting thing, in Outlook 2003 the httpmail:read value is not true or false, but 0 & 1. Thank goodness for the QueryBuilder.
