If you encounter a problem that cannot be solved by using the Outlook Express Troubleshooter, you might need to call your Internet service provider (ISP) or LAN system administrator. The connection settings or account information provided to you by your ISP or system administrator might be incorrect, or the ISP's servers or software may not be working properly.
Before contacting your ISP, you can create a log of the commands that have been sent to and from your mail servers. This can be useful for 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, and then select your server log from the Find results list.
