Using a 365 hybrid environment. Users cannot send to a specific internal distribution list. The emails are stuck with a delivery status: expanded. I am already aware on how to trace emails as that is the only relevant advancement towards a solution out here on the web. But after I get the trace results and realize it is "expanded" what is that really explaining? Why are the emails being held in limbo somewhere and how can I resolve this issue?
I have the trace:

There is also the message "The Message is awaiting submission to the mailbox store" which I cannot really make heads or tails of. What I do know is...
- emails are not being received for anyone attached to this specific distribution list.
- There is no way to force them from what I find.
- No failure notices or NDRs are received.
- This was working before 04/28/2014.
