Error when trying to send email using "send SMTP mail message"

Hi everyone,

So what I am trying to do is send an email to a recipient using send SMTP mail message activity based on a specific field. However, I am getting an error when I run it and it does not really point me in the direction on how to fix the problem. This is the error:
Send SMTP Mail Message: An error occurred while attempting to establish an SSL or TLS connection.

The SSL certificate presented by the server is not trusted by the system for one or more of the following reasons:

  1. The server is using a self-signed certificate which cannot be verified.
  2. The local system is missing a Root or Intermediate certificate needed to verify the server’s certificate.
  3. The certificate presented by the server is expired or invalid.

See https://github.com/jstedfast/MailKit/blob/master/FAQ.md#InvalidSslCertificate for possible solutions.

Has anybody had this problem and found how to fix it ?

Thanks in advance
