Hello, I user Exch 2007. For some reason that I can NOT explain the members from a DG has been removed... And this for a week. I have been able to track and identify the senders but I am wondering if I would be able to retrieve the email received on DG with empty members? Thanks, Graig

You won't be able to do much about external email sent to the DL, but you can find out who sent to it internally and ask them to re-send by searching the message tracking logs.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Nope. Messages sent to a DL with no members simply disappears.
