Support to send EMAIL using Outlook Account via TLS1.2 on BW6 6.3.2

Microsoft will no longer support TLSv1 neither TLSv1.1 to send e-mail using an outlook mail account to

While using BW 6.3.2, I was expecting it to be a simple configuration update on sslClientResource from SSL Protocol TLSv1.2 but even after doing so, I still get the below error after testing:

TIBCO-BW-CORE-500051: Activity [sendErMail] fault. Error sending mail message.-{ActivityName=SendErMail, ProcessName=TcomMailDelivery.service.TcomMailDelivery_MainService,} TIBCO-BW-PALETTE-MAIL-500036: Error sending mail message.

javax.mail.AuthenticationFailedException: 421 4.7.66 TLS 1.0 and 1.1 are not supported. Please upgrade/update your client to support TLS 1.2. Visit []


What else is necessary to enforce the usage of TLSv1.2 on BW6
