Hi Exchange Community! How can one tell the last time an e-mail was sent to a particular distribution list? We're interested in this for auditing purposes. Thanks!

I don't believe there is, unless you maintain your own usage stats. I have a PS script I run ervery day that goes throgh the previous days logs and accumulates various stats. One of them I accumulate is DL usage stats. Edit $hts for your hub transport servers, and this will give you a list of which DLs were used so far today, and how many times: $hts = "exch-hub1","exch-hub2" $dls = @{} $hts |% { get-messagetrackinglog -server $_ -EventId expand -start (get-date).toshortdatestring() -resultsize unlimited | % {[int]$dls[$_.relatedrecipientaddress] += 1} } $dls[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Hi Mike, I would use the script below: get-messagetrackinglog -recipients "DLname@domainname.com" -resultsize unlimited |select-object recipients,timestamp |sort timestamp -descending You could get a list of the emails which sent ot the DL, and the latest one on the top.
