Your options for building such an application would depend on such things as:

-- where the contact data is stored (e.g. PST file vs. Exchange public folder)
-- if Exchange, what version
-- network security issues related to external access by the offline agents
-- Outlook version

etc.

I just want to insulate my user from having to go through outlook, the
scheduling is used but the the data feeds other forms and reports.

Since Outlook already provides the ability to update contacts in any
contacts folder for which the user has permission, how does what you want to
do differ from that built-in functionality?

I want to give the enduser access to updating phone numbers, addresses etc
the generic C.R.U.D. features usually associated with a database, but
performed against the contact list.

Adjust the contact list in what way beyond the usual opening a contact,
changing it and saving it?

I am using the outlook contact list as the base of a sales list, that is
uded by off-line field agents. I would like to implement an edit ability
from my program to adjust the contact list is this possible -- if so is
their a tutorial to get me started?
