In Exchange Server environments where mailbox audit logging is used there may be a need to regularly generate reports of mailbox audit log data. I've written a PowerShell script, Get-MailboxAuditLoggingReport.ps1 to perform this task.
Although mailbox audit log reports can be created in the Exchange Admin Center the interface is not as fast to use as PowerShell, and it can't be scheduled to run automatically for regular reports like a script can.
This script will generate a report of the mailbox audit log entries for a specified mailbox, for a period of time (the last 24 hours by default), and save the full results to CSV as well as a summary of the data to a HTML file. The script can also be used to send the results via email with the CSV data attached.
