I am experiencing an odd issue. I have Exchange 2003 running on a WIN2K3 Server. I have been receiving duplicates of messages of several e-mails. I can't seem to find a pattern and at least a few users are affected by it. If I look at the messages in the message tracking center I can see the message process through to normal delivery, then a few hours later, it processes through to normal delivery again....and again and again. It does not happen with every message nor has it affected every user yet. I have never seen this and am not sure where to turn to resolve. Any ideas?
