I'd say this could be done either in Access or in Outlook. The
advantage of Access is flexibility and expandability; Access'
disadvantage would be that it'll take much more work to create the
application before you can start entering contacts. The advantage of
Outlook is that mailing lists and contact entry forms are built in
already and don't need to be reinvented; the disadvantage is that you
don't get the power of a full database.
