Quick Answer
This error means Outlook could not reach the mail server within the timeout period. Common causes: incorrect server hostname (should be mail.yourdomain.com), your IP may be blocked by the server firewall, or your ISP is blocking port 110. Switch to POP3 over SSL on port 995 to resolve most cases.
