When you created your mailbox profiles you have a check box which enables or disables the creation of an HL7 message traffic log. If checked then a text file (.txt) will be created daily in the \TrafficLogs sub-folder of the profile's mailbox folder. The traffic log is a TAB delimited ascii text file which can easily be opened with Microsoft Excel or any text editor (like Notepad etc.)
