The OLE interface for outlook is pretty well documented, you could easily
write a Delphi application that synchornised the two pieces of data.

How many contacts are you talking about in total & how often do they change?


Certainly FB -> Outlook would be easier, but you always have the problem
when they change the record outside FB and then you have lost sync.

I haven't done this with outlook, but with Act many years ago and that was
with DDE, not OLE.
