I have just learned how to construct a database in excel so that I
can sort my customers by the products that they buy (using filters).
What would be useful is to do this with my contacts in Outlook 2000
so that I can ask "which customers by product "A" and just those
contacts would appear - is this possible?

Assign a category of "Product A" to those contacts who purchase that product
and then group by category.
