XADM: Empty Notification-Requests Bitstring Causes Conversion Error and NDR

• Microsoft Exchange Server, version 4.0

SYMPTOMS

The Microsoft Exchange Server message transfer agent (MTA) fails to handle a legal encoding of the P2 field notification-requests. The content conversion process from P2 to MDBEF fails and a non-delivery report (NDR) is generated.

The following event IDs may be seen:
