SYMPTOMS
========

When a message returns to the sender with a NDR (Non-Delivery Report), the
PR_NDR_REASON_CODE and the PR_NDR_DIAG_CODE appear on the recipients that did
not receive the mail. When you try to resend this message to one of the
recipients that did not receive the message, these properties should be removed.
However, these properties will still appear for the recipient on the newly
created message.

CAUSE
=====

These properties are not being removed when the message is re-created.

RESOLUTION
==========

To avoid unnecessary processing of messages with these properties, check the
message class. The message class, stored in PR_MESSAGE_CLASS, is
REPORT.<subject message class>.NDR for non-delivery reports.

STATUS
======

Microsoft is researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
