We are running Exchange 2003 SP2. We recently migrated some users off an Exchange 5.5 server, not part of our current Exchange organization. Along with them we created Distribution Lists on our side to mirror the lists they had in their 5.5 org.
The problem that we are seeing is that some of these Mailing Groups have other, smaller mailing groups as members. For Example: "All Users Company1" is a mailing group. It has "All Users City1, All Users City2, and All Users City3" as members. It would appear that when someone sends to All Users Company1, not all of the member lists receive the email.
I've been able to track some messages and the tracking shows that it delivers to some of the members but apparently doesn't even attempt to deliver to others. Has anyone seen anything remotely like this? Anything that I can check on my end to try and resolve the issue? We have deleted and recreated the parent Mailing Group for some of these. On some it worked, on others it has not.
