Incoming email server: You can get this information from your ISP or administrator. Usually, an incoming mail server address is in the format of mail.contoso.com or imap.google.com. For many email accounts, you can find this information in the POP and IMAP server name reference provided by Microsoft.Outgoing (SMTP) email server: You can get this information from your ISP or administrator. Usually, an outgoing email server address is in the format of mail.contoso.com or smtp.contoso.com.

The servers are set up to use the server name (mail.contoso.com) followed by a colon (:) and then the port number followed by another colon and then another number (usually 1).  If the server name is valid, you will only want to change the number between the two colons.
