I use MSOutlook / Exchange for calendaring at work, and KOrganizer at
home. Getting between these two has been a trick, till I found a
Windows based product called OutLook2Mac.

Works like a dream and seems to handle duplicates cleanly. Also does
your email and contacts, but I haven't gotten that working (yet)...
The best part is that at $10 it is very reasonably priced.
Anyone with advice on a free or cheap way to get my contacts cleanly
into kaddressbook please feel free to comment...
