Microsoft 365 Mail traffic reports

Mailbox traffic reports help you analyze your organization's Microsoft 365 mailbox traffic with invaluable information such as the volume of spam entering and leaving your organization’s mailboxes, the users who send and receive the most mail, and the users who receive the most spam and malware.

This information helps you easily identify any mail activity anomalies, whether they originate from or are directed to a particular mailbox, which is a clear sign of malicious activity. This is rarely intentional—it is most often a spamware behind these anomalies. But using the data gathered from mailbox traffic reports, administrators can identify the issues, if any, before they disrupt the user.

With M365 Manager Plus, the complete Microsoft 365 solution, these reports can be scheduled to run at fixed intervals, emailed to administrators, and exported to CSV, XLSX (Microsoft Excel), PDF (Adobe Acrobat), or HTML formats.
