All About the Get-MailTrafficSummaryReport Cmdlet

The Get-MailTrafficSummaryReport cmdlet gets a lot of praise in some quarters. I am not so impressed. The Exchange Online cmdlet is useful, but it’s now showing its age in a world when better data to create a view of user activity is available elsewhere, notably in the Microsoft Graph. This doesn’t mean that the cmdlet doesn’t do a good job; it’s just that it hasn’t received much love from Microsoft since 2015.
