Can it be done within Outlook itself - as far as I know, the answer is <no>
without writing custom code and then you would have to also deal with the
"automation" portion of the requirement.
Some adhoc comments:
Using the Outlook import wizard----
a) restricted to Outlook's definition of what a "duplicate" is (= Name
and Email fields). Have also found Outlook to be "moody" when importing from
a file and specifying "Replace duplicates with items imported"
b) can't be scheduled (leastwise not that I'm aware of)
c) can't involve custom form/fields
Writing your own code:
a) There are numerous code examples online on how to update Outlook
fields (i.e.
http://www.outlookcode.com is a good starting point). Whether
this is an easy/hard/fast/slow path to follow is both subjective and
relative. My car mechanic tells me most things he does are real easy -
"anyone can do it" and I believe him. Problem is I'm not remotely interested
in finding out, don't have the tools, and most importantly, too many other
things that need to get done within the available time. Ergo, if your not a
programmer, may take a little bit of extra time to change some of the
available code samples but certainly do-able. It's also <much, much> easier
than creating a generic public solution since it only involves your system
and data (i.e. contact folder, data file and fields are known).
