Did you actually follow that link and read the document? It clearly says what to do:

"Legacy clients and devices will need to be configured to submit using the new endpoint smtp-legacy.office365.com"

HTH...

Updated the below change in jenkins server , I am able to trigger mail approvals to respective team members

@derrick.mcc...@gmail.com 

Open /etc/sysconfig/jenkins and edit JENKINS_JAVA_OPTIONS as follows ::

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dmail.smtp.starttls.enable=true -Dmail.smtp.ssl.protocols=TLSv1.2"
