TITLE   :XADM: Truncated Text Returned If CDO Runs as a Service
PRODUCT :Microsoft Exchange
PROD/VER::5.5,5.5 SP1,5.5 SP2,5.5 SP3,5.5 SP4
OPER/SYS:
KEYWORDS:kbExchange550preSP5fix

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

 - Microsoft Exchange Server, versions 5.5, 5.5 SP1, 5.5 SP2, 5.5 SP3, 5.5 SP4 
-------------------------------------------------------------------------------


SYMPTOMS
========

When you run the Collaboration Data Objects (CDO) application as a Microsoft
Windows NT service, if a message body contains double-byte character set (DBCS)
characters, the Exchange Server information store may return a truncated message
body.

CAUSE
=====

When the CDO application runs as a Windows NT service, CDO uses Unicode text to
get the message body. Because the message body is stored as American National
Standards Institute (ANSI) text, the Exchange Server information store converts
the ANSI text to Unicode text. This problem can occur during the conversation if
a DBCS character spans the 16 kilobyte (KB) boundary.

RESOLUTION
==========

A supported fix is now available from Microsoft, but it is only intended to
correct the problem described in this article and should be applied only to
systems experiencing this specific problem. This fix may receive additional
testing at a later time, to further ensure product quality. Therefore, if you
are not severely affected by this problem, Microsoft recommends that you wait
for the next Microsoft Exchange Server 5.5 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services
to obtain the fix. For a complete list of Microsoft Product Support Services
phone numbers and information about support costs, please go to the following

NOTE: In special cases, charges that are normally incurred for support calls may
be canceled, if a Microsoft Support Professional determines that a specific
update will resolve your problem. Normal support costs will apply to additional
support questions and issues that do not qualify for the specific update in
question.
