Hi Dhage, Endraja (CIB Tech, IND),

Thanks for reaching out. Please check if the message was not blocked on the recipient end. Also check the Sent Items folder of the sender mailbox to see if it contains the sent message or if an NDR was received in the Inbox. I was able to test the graph api call and response body mentioned in the article you provided via Graph Explorer (aka.ms/ge) with message successfully delivered to recipient mailbox.

Thanks.
