Change SMTP Port in MS Outlook


OutlookIf you can’t send email and you’re using a commercial ISP , they may be blocking SMTP port 25. This port is standard for sending email. But it’s also standard for sending spam, so ISPs often block it.

In order to send email again, you’ll have to change to a different port number. AVANetwork recommends use either Port 2525 or Port 587.
