SYMPTOMS
A program that is written in Microsoft Visual Basic may not be able to read Message Queuing messages that have been rejected and stored in the MSMQ-MQSeries Bridge Dead Letter queue.



CAUSE
When MQSeries rejects a message whose message body contains a Component Object Model (COM) object, the MSMQ-MQSeries Bridge changes the value of the PROPID_M_BODY_TYPE property to VT_BLOB (instead of maintaining the original variant type that is assigned to PROPID_M_BODY_TYPE). As a result, Visual Basic applications cannot read the message from the Dead Letter queues because VT_BLOB is not a known variant type.
