Outlook 2003 Error: Your outgoing (SMTP server does not support SSL secured Connections)

Symptoms: You are unable to send mail from Outlook and the error message you may receive is that your outgoing smtp server does not support SSL Connections.

Solution 1 of 2: Confirm your Email provider uses an SSL connection, if they do NOT use an SSL connection, go to Email Accounts > View or Change > Select your Account > Change > Select More Settings > Navigate to the Advanced Tab > And Uncheck SSL for outgoing mail server.

Solution 2 of 2: Your Server Requires an SSL Connection.   Go to Email Accounts > View or Change > Select your Account > Change > Select More Settings > Navigate to the Advanced Tab > Under Outgoing SMTP Server change the port from 25 to 465, make sure SSL stays checked.

The default port for SSL secured SMTP traffic is 465, many internet providers will block port 25 by default.
