Scenario:
Leveraging Microsoft 365 and Microsoft Dynamics with a primary email domain (XYZ.COM). Additionally,with three custom domain names in Azure, which are used with Microsoft Dynamics. These domains are verified with an IMAP email service that is not Microsoft 365.
Issue:
When attempting to send an email from primary domain (XYZ.COM) to any of the three custom domains, received a non-delivery report, even though other email services can send to these domains without issue. However, once you remove the custom domains from Azure, you can send emails normally from XYZ.COM to these domains.
