Emails notification not sending out of JDE

Hi Team,

Since yesterday 31/Oct/2018 , JDE is not sending email notification.

SMTP server connection is intact.  No change in JDE SMTP setup.

Could you please tell me which version of TLS protocol supported in JDE for 9.2.2.2 TR and 9.2 application release, WLS 12C.

Is it TLS 1.2?

We are on Microsoft Office 365.

Received this from Infra team:

----------------------------------------------------------------

As of October 31, 2018, Office 365 will no longer support TLS 1.0 and 1.1. This means that Microsoft will not fix new issues found in the client, device or service that connects to Office 365 using TLS 1.0 and 1.1.

Please note: TLS 1.0 and 1.1 will continue to function but are no longer supported. We will provide additional notification prior to retiring TLS 1.0 and 1.1 completely.
