Getting Error and failed delivery message when I use my Outlook email

Question

Hi Microsoft TechNet Team,

We have a company email which is ******@hudsonathenslighthouse.org.
However, each time a receive a reply, my inbox shows the message "Delivery has failed to these
recipients or groups..." with a string of coding, seems like. Scroll below to see the details.

This has not happened to me before and I don't know how to fix this since I am not tech-savvy.

Please help!

Thank you in advance.

Best Regards,
Kathleen

Answer 1

Hi @Hudson Athens Lighthouse Events ,

It seems your Exchange Online tenant administraor has configured some outbound spam filter policies to control automatic forwarding to external recipients or for this email address (******@hudsonathenslighthouse.org). Please refer the below documentation for more information on this :

https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/external-email-forwarding?view=o365-worldwide

You can also look into this tech community post for additional details on this issue. I would advise you to reach out to your Exchange Online administraor with this information to troubleshoot and resolve this email delivery issue for this email address : ******@hudsonathenslighthouse.org

Hope this helps.
