Preeti321 Any specific reason you want to send emails from your Tenant Address and not your own Custom Domain ?

Please go through FAQ for Domain in Office 365 - https://docs.microsoft.com/en-us/office365/admin/setup/domains-faq?view=o365-worldwide

Additionally, are you a Microsoft Vendor (working for Support Projects) worldwide? If yes - Please reach out to your Technical Advisor for unblocking the Test Tenant you own, internally !!

If not, and you are only using it for your Own Learning and testing, you should not use domain.Onmicrosoft.com address for sending emails (except) testing.

Please delist your Tenant and IP by opening a Microsoft Support ticket.

Cheers !
