Track messages with message id

Message tracking is easier and faster with message id. This message can be retrieved from Ironport. So if you can get message id from Ironport, hand-off server name and time, the search will go better and quicker. While in Exchange powershell, use the command below to find the message status and export to CSV file.
get-messagetrackinglog -Server "ServerName" -MessageID "<BE2BA0B06D1DF24AA8FBE8319637DC3F051EB07205@MAIL1.TEST.org>" -Start "4/12/2010 1:06:0
