    Error: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM

      Hello,

       

      I have configured my SMTP server to use Office365.

       

      I get the following error when I try to email a report in NPrinting 17.3

       

      The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM


      How to solve this issue please?


      I am using:

       

      smtp.office365.com

      Port: 25 (also tried 587)

      Domain\MyID

      Network password
