Since the true SMP server is a third party (outlook.com), which needs TLS encryption, I have setup the local IIS SMTP server to relay the emails.
On my code, I don´t assign the parameters listed above so that the email is sent to the local smtp server for relay.
I am getting an mergeErrorMsg : "The SMTP server requires a secure conection or the Client was not authenticated. Server Response 205.7.1 Client was not authenticated".
Can you please advise!
