We have a computer, XP Pro SP2, Outlook 2003 and 2 logins. On one login, we can get email in the morning. When we come home for lunch, Outlook can't find either the incoming or outgoing mail servers, even if we reference them by IP address. If you logout and login it doesn't help. If you restart the machine, it works. The other login doesn't do this. While the error condition exists, creating a new email account or even a new Outlook profile doesn't help.
