    Hi @Gurudas ,
    You also need to create a relay connector in office 365 if you have prepared your application.
    I found this guide which shared the complete operation on how to relay emails through office 365 , this should be helpful to you : Configure Office 365 SMTP relay - ALI TAJRAN

    Hi @Gurudas ,

    It has been a few days and I am checking in to see how things are going on with this issue.
    Did the guide in the previous post help you successfully configure the required SMTP relay?
    Here I found an official document that explains in more detail how to configure mail relay from the app to O365. Hope it helps!
