@Abhijith ClaySys - The above answer was correct till last week. But last week at Microsoft Build 2021 conference, we announced a new feature so that you can use Microsoft Graph with S/MIME, encryption etc. You may want to get it started from here.

Is it possible to send secured/encrypted emails programmatically using Microsoft Graph API? (Or any other APIs under the Microsoft product family). If yes, can you please share some documentation links for that?

2021-05-28T02:26:19.59+00:00 I really appreciate you taking the time to share your thoughts. As of this time, however, the related Q&A indicates sending encrypted email programmatically with Graph API is not supported. And can this reference help you ?
