Email subscriptions using Office 365 not working

Email subscriptions using office 365 are not working. They were working before with on premise exchange server. Updated email settings to use Office 365 smtp server with Basic Authentication (username and password) and getting the error below:


System.Net.Mail.SmtpException: Failure sending mail. ---> System.ComponentModel.Win32Exception: The client and server cannot communicate, because they do not possess a common algorithm


Tried to change the port from 25 to 587 to no port. Restrarted the server. TLS 1.0 is already enabled.


Any suggestions on what I am doing wrong?


Here are the settings in the config file:
