SMTP Authentication in Outlook for the MAC

• First locate the Tools menu. Click on that, then select Accounts
  You should be looking at the "Account Settings" tab
• Look near the bottom under the SMTP Server and click on "Advanced Sending Options"
• Check "SMTP Server Requires Authentication"
• Also check "Use the same settings as Incoming Mail Server"
• Click OK

Norton Anti-Virus Users: If you are using Norton Anti-Virus on your system, you must enter the username and password in the SMTP Authentication settings of your email program. In other words, you cannot use the "Use the same settings as the incoming mail server" option, you must use the "Login As" option and re-enter your username and password.
