Issue: NDR When Running Python File via Microsoft Graph API
Hi everyone,
I'm experiencing an NDR (Non-Delivery Report) error when running a Python script that uses the Microsoft Graph API. Here is my current setup:
- Trial tenant
- App registered in Azure Portal
- Required permissions granted
- Inbound connector configured in Exchange admin centre
- Python code being executed from a VM (workgroup)
Error Details:
email address removed for privacy reasons
Remote server returned '550 5.7.708 Service unavailable. Access denied, traffic not accepted from this IP. For more information please go to http://go.microsoft.com/fwlink/?LinkId=526653 AS(7186).
I've followed the documentation and believe I've set up everything required. Is there any step or configuration I might have missed?
Any guidance or suggestions would be greatly appreciated.
Thanks!
Hi,
Sending e-mails thru PS/GAPI in trial subscription is by default blocked by Microsoft. Open request ticket from admin 365 portal. They will change it.

Hi Matich3ck ,
Yes, I have submitted the request to Microsoft, and they have added the trial tenant ID to the sending exclusion list.
Thank you for your support.
Ensure that the Graph API has the Mail.Send permission, check the email header format, and avoid NDRs.
Hi Belicke ,
Yes. I have already added this permission in Azure portal
