Due to the duplicate messages detection feature in Exchange, user will only receive one copy of any duplicate message. Any duplication will be discarded by Exchanges.

The typical scenario is you are a member of a distribution list and you will only receive one copy of the message when you send to that particular distribution list and CC to yourself. More information can be found at Microsoft at:
