Hi @nitesh-sharma1. Thanks for being part of GoDaddy Community! Given that you're posting this to our Office 365 board, I'm guessing that you're trying to use an Office 365 account to relay your email. That is not possible with the email plans we provide. You may need to look into other relay providers, such as Mailgun. The only websites that can relay messages via our email servers are those that are hosted with us. Even then, you would only be able to use relay-hosting.secureserver.net. I hope that helps clarify the situation.
