Article: Q288722
Product(s): Microsoft Exchange
Version(s): 5.5
Operating System(s): 
Keyword(s): kbExchange550preSP5fix
Last Modified: 22-JUL-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

When you send messages with attachments on a server running a third-party
antivirus product that uses the Exchange Antivirus application programming
interface (API), you may receive non-delivery reports (NDRs) that contain the
following information:

- Reason code = transfer-failure

- Diagnostic code = invalid-arguments

Also, an event ID 2025 error message from "MSExchangeIS Private" that contains
the following text may be logged in the Application event log:

  The delivery of a message failed due to error BB8 (or 50A). A non-delivery
  report is being sent to the message's originator.

CAUSE
=====

This problem can occur if a user (user1) has an autoforward rule to another user
(user2), and a message with an attachment is sent to both users (user1 and
user2). User2 receives two messages, and the attachment needs to be scanned two
times by the third-party product.


RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
correct the problem that is described in this article. Only apply it to systems
