Server is actually Exchange 2007 SP3
I have a DDL (one of about 150) and a couple related Hub Transport rules that cc a handful of other individuals when this particular DDL is in the To or CC fields.
If I preview the membership in either EMC or EMS I see the proper list of members.
If I email the DDL it expands to no members (according to Message Tracking Event ID EXPAND) - no errors as far as I can tell, but no members. Message Tracking shows two result: RECEIVE and EXPAND. After that it just disappears and the related Hub Transport rules are not processed.
If I email the DDL and cc myself it will still expand to no members but the Hub Transport rules kick in and those people are cc'd on the message. In other words, the people cc'd via Hub Transport rule get the message but the actual members of the DDL still do not.
Any ideas out there on what might be causing this?
Remove those users from DDL and add them back and check the issue.
I assume rest of the DDL's are working fine.

Does this issue occure in OWA? Please using OWA for testing.
If it works well in OWA, it seems an issue on the Outlook Client side.
Please run Outlook under safe mode to avoid some AVs, add-ins and firewall.
Please try to re-create new profile to refresh the caches for testing.
About the "How would I remove a user from a DDL?"
A dynamic distribution group includes any recipient in the Active Directory directory service with attributes that match its filter. A recipient that is not expected to be part of a dynamic distribution group could inadvertently become a member and start receiving messages sent to the dynamic distribution group if the recipient's properties are modified to match the filter.

If it still not works unfortunately, please try to re-create a new DDL for testing.

I don't think I was clear in my first post, let me clarify. This is a dynamic distribution list. The suggestions here all assume it's a static distribution list. Dynamic lists are expanded on the server - not the client. The failure is occurring at the hub level.
I'm very against rip out and rebuild solutions. First, it's breaks Outlook PC clients that have it in their quick-fill list until they clear it out. Second, that doesn't really solve the problem. R&R should only be considered when it's known that is the only way to fix.
I got this resolved - I didn't have the container properly specified. Apparently when you preview a DDLs membership, it ignores the container setting.
