This is an example of a Message Tracking command that I use most:
Get-Messagetrackinglog -ResultSize Unlimited -Recipients:user@contoso.com -EventID "RECEIVE" -Start "09/25/2016 4:30:00 PM" -End "09/30/2016 5:17:00 PM" | select-object eventid,timestamp,messageid,sender,recipients,messagesubject | Out-GridView
These are the parts that will improve search results and make it easier for you to understand the results:
-ResultSize Unlimited specifies the results should include everything
The select-object part shows the objects that need to be shown in the results, the most common objects are listed here.
Out-GridView sends the output to an interactive table in a seperate window.
OPTIONAL PARAMETERS:
-Recepients specifies a specific recepient (or multiple, seperated by a comma)
-EventID is where you can choose what event you want to view (RECEIVE, SEND, FAIL…)
-Start and -End makes the result show a specific timeframe and needs one of these format: “Sep 25 2016” or “09/25/2016 4:30:00 PM”
