Export list of all external senders (Exch2013/ExchOL)

Is there a way in PowerShell to export a list of all external email addresses that have sent to my company's users, say over the past month, in Exchange 2013 or Exchange Online?

You could do this using the Message Tracking Log in Exchange management Shell providing your logs go back far enough:

-getmessagetrackinglog -resultsize unlimited -start "12/01/2017 00:00" -End "01/01/2018 23:59" -EventID "Deliver" | select Sender, Recipients

You will want to output it to a text file or csv.

Thanks Andy, that will work on my Exchange 2013 servers, any ideas about Exchange Online? I realize that I'm limited to 30 days only.

Get-MessageTrace -Resultsize Unlimited -StartDate 12/5/2017 -EndDate 1/4/2018 | Select Received,SenderAddress,RecipientAddress,Subject | Export-CSV C:\MessageTrace_Results.csv -NoTypeInformation

-Resultsize Unlimited parameter wont work, and without it, it seems like the output is limiting the results to 1000.

Yep, one would think that I could get more than 1000, but even the 5000 parameter wont work unfortunately.

$dateEnd = Get-Date
$dateStart = $dateEnd.AddDays(-30)
Get-MessageTrace -Resultsize 5000 -StartDate $dateStart -EndDate $dateEnd | Select-Object Received,SenderAddress,RecipientAddress,Subject | Export-CSV C:\MessageTrace_Results.csv -NoTypeInformation

A parameter cannot be found that matches parameter name 'Resultsize'.
