Once you have this option enabled, the application troubleshooting log starts registering all information about interaction between MS Outlook 2003 / 2007 / 2010 and a mail server each time a message is sent/received.
Information Important notice: once you are over with troubleshooting, disable the logging. Otherwise the log file will keep growing, and that can potentially lead to a lack of empty hard disk space.
Log file location
For POP3, SMTP, MAPI protocols
For IMAP protocol
Information Sometimes the data can be registered in the log only after closing MS Outlook.
