When a Receive Adapter receives a message it is passed to a Receive Pipeline before going to the message box.
The Receive Pipeline is the component that would do the De-Batching and therefore the above statement is still true.
In the BizTalk Admin console you can check the “Enable Routing of Failed Messages” check-box and you can create an Orchestration to receive these messages. Set the Receive Shape Filter to ErrorReport.ErrorType == “FailedMessage”
