The Exchange Server uses a 'connector' to send the email and the properties for the smtp connector allow you to setup smtp authentication.
You will need to insert the username and password for a legitimate mailbox that is already setup on our server.
Make sure you turn authentication on and use the mailbox username (which is the email address) and the mailbox password (as used when setting up the email mailbox) to authenticate.
TLS encryption may or may not be accepted depending upon your setup.
