Unfortunately you still haven't identified where the individual user
contact's reside - "local PST file" or in a personal Exch folder
(assume you're not using a global contacts folder at this point).
Makes a big difference in how things get implemented.
There are various potential 3rd party solutions to this as well
which you can find and may want to look at on
http://www.slipstick.com.
From our experience, the term "sync" can identify a great many
issues within an organization when there are no firm rules in
place for such things as duplicates, master data ownership and
the like. As for CG, we only have one-way products that will
update either contact folders (on import) or databases (on
export) but currently haven't released a "two way multi-contact
folder" sync product as of yet. "Syncing" between any two single
data sources is a lot easier then when dealing with an equation
that includes a one-to-many scenario (such as mutiple contact
folders where there are no firm rules for "uniqueness" or "ultimate"
data ownership). Have seen very few solutions that actually work
long term beyond the most simplistic of environments.
Generally, a true an full "sync" needs to address things like:
#1 - Can each contact be absolutely uniquely identified by some
data field(s) to avoid duplicates?
#2 - When duplicates are found - how will these be handled at the
contact folder level and DB level?
#3 - If a contact is deleted from the master database - does it in
turn get deleted from the contact folders?
#4 - Which data source has priority? If a change is made to a
contact in a folder but deleted from the DB the same day -
does it get re-added?
#5 - When does a contact get deleted from the DB? When the
first person deletes it from their folder or when no one
references the contact or by the DB Admin?
#5 - What's the priority of changes? Those made to the DB or
"last in"?
....................list of questions can goe on and on but all depends
on actual requirements/objective and importance of info.
