I have added "Distribution List" email Id as Contact in dynamics and sending an email to the Contact.
It fails to send the email. However, I can send emails from outlook to the same list successfully. I wonder what stops to reach emails to the recipient's mailbox when sending from Dynamics.
Please help to resolve. Below is the failure email received.
Delivery has failed to these recipients or groups:
(XXXXXXXXXXXXXX@XXXXXX.com)
Your message can't be delivered because delivery to this address is restricted.
For more information about this issue see DSN code 5.7.1 in Exchange Online.

I have the same question (0)Hi,
I am not an expert on Exchange but looks like you have some rules to restrict the email.
