I'm trying to set up my contacts in Outlook 2003 and am trying to find
out the most efficient way of organizing them using folders and
categories. Let's say I have 3 categories of contacts, A, B and C.
Some contacts may belong to more than just one category. One thing I
often have to do is an email merge. So I'd like to be able to select,
say, all emails belonging to categories A and C. I suppose the way to
do this is put all contacts in one outlook contact folder and assign
them categories A, B, C as needed.

However, for other purposes, it would be nice to have not all my
hundreds of contacts combined in just one single folder. It does not
seem very organized, even if each contact is "tagged" with its
respective categories.

So what's the most efficient way of organizing my contacts, between
putting them in different folders and tagging them with categories?

For instance, is there a way of globally extracting contacts by
category if they reside in separate (sub)folders?

Thank you.

Marc.
