Disable NDR for DLs in O365 Hybrid Deployment – How to Guide

exchangemicrosoft-office-365

Is there a way to disable the delivery of NDRs when emailing a larger internal DL? Some of users are on O365 and some are on on-prem exchange.

There are methods for on-prem exchange but I can’t find anything for hybrid or cloud.

Thanks

In Exchange server or Exchange Online services, we can only disable non-delivery reports to the remote domain.
