Change Outlook SMTP Port

This article goes over changing the SMTP port within Outlook.  This is required if you are not able to connect over port 25 or your ISP is blocking the port.  Our alternate port is 50.  The common errors you may receive if you need to do this are below:

The connection to the server has failed. Account: 'Your Name', Server: 'mail.domain.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

Task 'Account Name - Sending' reported error (0x80042109) : 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

1. Open Outlook.  Within Outlook, navigate to the Tools menu and select Accounts.
2. Double-click your account and click More Settings button.
3. Navigate to the Advanced tab and change the SMTP port to port 50.  Test the connection by opening a command prompt and entering in the following (where mail.domain is your email domain or email server):
telnet mail.domain.com 50
