Pega 8.1 - SMTP send failure STARTTLS - Office365 Outlook
In the Pega cloud environment, I am trying to connect to Office365 outlook with basic authentication with below config details.
Test connectivity is successful. But, getting the below exception as part of the outbound email.
[MSG][Unexpected exception caught while trying to send an email message.][STACK][com.sun.mail.smtp.SMTPSendFailedException: 451 5.7.3 STARTTLS is required to send mail [SJ0PR05CA0172.namprd05.prod.outlook.com] at
Attached the complete error log.
I tried with port 25 as well. Test connectivity is successful, still the same error.
