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=}]'.
-Strange time stamp
