To delete log files used for troubleshooting
To troubleshoot communication problems, you can set up Outlook Express to log all commands to and from mail and news servers. These files can get quite large, so it is important to remove them when you are finished troubleshooting.
Log files are named by server type and have a .log extension (for example pop3.log, smtp.log). If you don't know the exact name of the log file, type *.log.
