550 5.7.60 smtp; client does not have permissions to send as this sender

[Anilkumar]

Mails are not getting delivered to recipients from SAP application. Receiving below error when users try to send email from SAP application.

We can see the error in BAD email in SMTP server,

Error: smtp; 550 5.7.60 smtp; client does not have permissions to send as this sender

Hi, Anilkumar.

Are you guys using an Exchange Mail Server?

I did some research on this specific error message *"550 5.7.60 SMTP; Client does not have permissions to send as this sender"* (what will make sense if you guys are using Exchange Server) and we were able to find these pages that might be helpful with this configuration:
