I use a number of different Distribution Lists for various purposes for
contacts that are in various groups. People (aka contacts) are continuously
joining and leaving organizations

Most of my contacts are associated with one or more categories, which has
been made much simpler and more streamlined with Outlook 2007. Is there a
way to automatically add (and remove) contacts with a given category to a
distribution list enmass rather than individually. Some of the lists have
100 + contacts.

Thanks in advance for any suggestions,
