Outlook 2007 stopped sending emails

No major changes were made to my system, but all of a sudden MS Outlook 2007 refused to send emails. ANY emails. I receive emails into all of my accounts, but can't send from any of them. I have run scanpst.exe, tried using new profiles, and disabled anti-virus scanning of sent emails.I have XP Professional and MS Office 2007 on a newer HO Probook 4710s. Any suggestions are appreciated. Thanks.

Hello,

Are you using SMTP/POP3? By default SMTP Port uses Port 25. Some email Providers tend to change their SMTP Ports. Try using Port 587, see if it helps. If not you shd contact your email provider.
