KEYWORDS:exc55 kbExchange550preSP4fix kbExchange550sp4Fix

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

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


SYMPTOMS
========

If you send messages produced by MAPI applications that use the
PR_CONTENT_CORRELATOR MAPI property, the messages may not be delivered to other
Exchange Server computers, and no non-delivery report (NDR) is returned. The
following error message may be logged in the application event log:

   Event ID: 246
   Source: MSExchangeMTA
   Type: Error
   Category: Internal Processing

   Description:
   An internal MTA error occurred. An attempt has been made to read beyond the
   end of an object. Attribute ID: 36. Object at fault: 06000033. Offset
   reached: 114. Contact Microsoft Technical Support. [MTA DISP:FANOUT 9 223]
   (14)

CAUSE
=====

This issue can occur if the Exchange Server message transfer agent (MTA)
incorrectly encodes the message in the MTA database when the Exchange Server
information store submits the message to the MTA for delivery. When the message
is read out of the MTA database for transmission, a read failure is produced
during the attempt to decode the message data.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
