When an external addressee is a member of multiple Contact Lists and all of those lists are used, does OL2010 "automatically" send only 1 copy of the message to him, or must Mail Options be set to avoid his getting duplicates? If the latter, how to go about it?

In most cases, Exchange will send multiple copies. I'm not aware of any way to avoid it, short of expanding the lists and removing the persons address. If the lists are in the GAL, Exchange will do a better job are sending only one copy.
