If you look at the raw source for duplicate messages, you will see that 
one of them will have several Microsoft-specific headers that the other 
does not.  I use a rule on Sent Messages that looks for one of these 
extra headers and then moves the message to another folder.  I expunge 
the contents of that folder from time to time.
