We can use the Search-MessageTrackingReport cmdlet to retrieve the message tracking report for a particular email. With this report ID, we can then pass it on to the Get-MessageTrackingReport cmdlet to get the full tracking information for that email.
However, if you are not used to these cmdlets, you might come across the following error when running your search:
Search-MessageTrackingReport email@example.com -Recipients firstname.lastname@example.org You aren't authorized to perform the search. You need to have permissions to search for the sender of the message or for every recipient specified.
This is because, by default, users can only track messages that they send or receive from their own mailbox. To overcome this error, simply use the BypassDelegateChecking switch which allows us to track messages for any user.
