Hi, 1. Try running Message tracking from Microsoft exchange Management shell. : get-messagetrackinglog -Recipients:recipient@DomainA.com -Sender "sender@DomainB.com" -Start "7/12/2011 12:45:00 PM" -End "7/12/2011 12:55:00 PM" |fl - make the required modification in the above command and try - Does this also fail? 2. What is the version of .net frame work installed on the server? .Net framework 4.0?
