Thank you for the reply, all this has been very helpful. One more
clarification below:

FIRST, As you indicated, the data is stored separate from the display
form.
Therefore, if we add new information fields to a form, how do the new
fields
get added to the database?

Each item gets the new field as the user enters data into it, using the
layout on the latest version of the form.

So, are you saying that the Outlook Data Store is transparently modified to
include this new field of information along with all the other contact data?

Is there a way we can preview a Data Store and see what information it
includes and what the field name associations are?

Will the new data fields be preserved when moving the .PST file from
location to location? Though this new information may not be visible unless
the new location includes the custom form designed to show the new fields of
information, correct?

Thanks,

Richard
