I would like to know how many users have configured and are using an auto-forward rule. From what I have so far is that such messages are flagged with 'Source = MAILBOXRULE'
I am working with the command to test the output and see what step to take next. I have generated output, so a hit should be returned, but the output show no results;
"Get-TransportServer | Get-MessageTrackingLog -Start "12/05/2011 15:00:00" -Recipient "<specific SMTP address>" -Sender "<specific SMTP address>" |FL MAILBOXRULE"
The desired result is to have a log-file showing all the users that have an auto-forward rule configured (name, source, sender are values I would like to have in the overview).
