thisissripriya on "[Plugin: WP Mail SMTP] configure windows auth for SMTP server and send mail through WP-Mail-SMTP"

Hi,
I have configured the windows in-built SMTP server to work with IIS and send mails through php. I am able to get it to work without authentication. I am able to use the WP-Mail-SMTP plugin in wordpress to send mails without authentication.
Could you please let me know how I can turn on authentication and then use the plugin to send mails from wordpress?
Thanks!
