Outlook 2013 uses different ports on your computer to send and receive email messages. The one that it uses to send messages, called the SMTP port, can vary depending upon the settings that your email service provider has configured. However, some Internet service providers (ISPs) block some outgoing ports, which could cause problems for you where you are unable to send messages.
Our guide below will show you where to find the outgoing SMTP port setting for your email address in Outlook 2013. You will then be able to change that port number to something else if you are attempting to troubleshoot an issue that you are having.
