Emails have just been dropped with no NDR. These are internal users messaging an internal distribution group. The support tech had no idea, and refused to escalate the case. When I did a message trace this is the error I got

 

Drop Reason: [{LED=250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded};{MSG=};{FQDN=};{IP=};{LRT=}]

 

Is there a way to escalate cases? I've heard nothing in over a day even after requesting an update.

That message is perfectly normal for emails sent to DLs, post the full message trace.

You need the message trace details, Get-MessageTraceDetail. And you can also check the traces to the individual recipients, especially the ones that are having issues receiving messages.

Where in office 365 am I allowed to use Exchange cmdlets?
