Microsoft has a basic script you can run on PowerShell to spit out audits of mailboxes to a .csv. The problem is The .csv does not include the message ID, so I can match it up with the id that shows up in message trace, and it does not show the sender's email address.
Hoping someone can show me what I need to edit in the .ps1 so it can include those things. The link below is where I got the auditlog.ps1
