Hi @Tom Hemmerle
Thanks for posting your query here.

This issue arises because the JournalingReportNdrTo address (designated to receive non-delivery reports for undeliverable journal reports) is set to the same email address as the recipient in a journal rule. Microsoft's guidelines specify that these addresses must be distinct to prevent potential mail loops and ensure proper handling of journal reports.

To resolve this error, assign a different, dedicated email address for the JournalingReportNdrTo parameter that is not used as a recipient in any journal rule. This separation ensures that undeliverable journal reports are correctly routed without conflicts.
