432 4.2.0 STOREDRV.Deliver; Agent transient failure during message resubmission

Question

I am having an issue where emails to specific users internal to internal are being successfully delivered, but [a duplicate is?] also getting stuck in the "SMTP Delivery to mailbox" queue, with the sender getting a "Delivery is delayed to
these recipients or groups:" "Remote Server returned '400 4.4.7 Message delayed" This only happens with emails to specific people in the organization, they get the email immediately after being sent, and everyone else works fine. This issue
started after we migrated the users mailboxs from Exchange 2007 to Exchange 2013 CU5, we did not notice the issue until we finished moving all user mailboxes to 2013.
Delivery Report of email to affected user:
Delivered
6/30/2014 11:20 AM mail.domain.com
The message was successfully delivered.
Pending
6/30/2014 11:20 AM
The message has been queued on server 'mail.domain.com' since 6/30/2014 11:20:15 AM (UTC-06:00) Central Time (US & Canada). The last attempt to send the message was at 6/30/2014 11:21:09 AM (UTC-06:00) Central Time (US & Canada) and generated the error
'[{LRT=};{LED=432 4.2.0 STOREDRV.Deliver; Agent transient failure during message resubmission[Agent: Mailbox Rules Agent]};{FQDN=};{IP=}]'.

Update 7/2/14:
Checked event viewer, and found that event ID 1051, erroring multiple times per second with message:
"Agent 'Mailbox Rules Agent' caused an unhandled exception 'StoreDriverAgentTransientException: Store Driver Agent was unable to send email.' while handling event 'OnDeliveredMessage'"
Ran Test-MailFlow on my mailbox, and the two know non-working mailboxes, For me it returned as successful, but showed as a Failure on the two other accounts. 
The test emails were actually delivered to the user mailboxes even though it shows as a Failure with the Test-MailFlow command:
From Exchange Queue viewer you can see the test emails stuck in retry, with the following information:
Identity: mail\3112\1395864371267

Hi S Calkin,
According to the error messages, I find following information for your reference:
1. About Event ID 1051
This warning event indicates that the transport agent referenced in the event description has encountered an unhandled exception while handing the event.
More details in the following article:
http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Exchange&ProdVer=8.0&EvtID=1051&EvtSrc=MSExchange+Extensibility
2. About "432 4.2.0 STOREDRV.Deliver; Agent transient failure during message resubmission[Agent: Mailbox Rules Agent]"
I suggest double check whether you have enough space. I find a similar case that caused by the low space, please see this:
432 4.2.0 STOREDRV.Deliver; Agent transient failure during message resubmission[Agent: Mailbox Rules Agent]
