I have a Master Contacts list under my All Public Folders tab, that all
personel have access to. There are several contact lists listed under the
Master Contact list, like sub lists. I am in the process of updating contact
information the Master Contact list, however, I am not finding these updates
in the sub lists.

If I update a contact in the Master Contacts, how do I get it to update in
the sub lists without having to update the sub list contacts individually?

Also, if a new sub list is created, how do I make sure that the information
will be updatable from the master contact list? I need to know so I may train
my coworkers on how to make an effective and updatable contact sub list .

I appreciate any assistance anyone can give me.
