TITLE   :XADM: PR_MESSAGE_FLAGS MSGFLAG_UNMODIFIED Bit Not Set Correctly
PRODUCT :Microsoft Exchange
PROD/VER:WINDOWS:5.5
OPER/SYS:
KEYWORDS:kbusage

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

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


SYMPTOMS
========

A MAPI transport provider explicitly sets the MSGFLAG_UNMODIFIED bit for the
PR_MESSAGE_FLAGS property of a new message during the call to the
IXPLOGON::StartMessage() method, and the bit is not set on the message when
delivery is set to the Exchange Server information store. If default delivery is
changed to a personal folder (PST) file, the new message will have the
MSGFLAG_UNMODIFIED bit set.

CAUSE
=====

The Exchange Server information store was explicitly setting the
MSGFLAG_UNMODIFIED bit for the PR_MESSAGE_FLAGS property only in the case where
the information store delivered the message. When a transport provider is
"receiving" new messages, messages are essentially created in the Inbox, not
delivered.


WORKAROUND
==========

To work around this problem, set default delivery for the messaging client to a
personal folder.

STATUS
======

Microsoft has confirmed this to be a problem in Exchange Server version 5.5.
This problem has been corrected in the latest U.S. Service Pack for Microsoft
Exchange Server version 5.5. For information on obtaining the Service Pack,
