TITLE   :XCON: PAB Address Parenthesis in DDA Converted to 040 & 041
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 EXC55SP3Fix

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

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


SYMPTOMS
========

Messages meeting the following criteria are undeliverable:

 - They contain an X.400 address that is generated in a personal address book
   (PAB).

-and-

 - The X4.000 address contains a domain-defined attribute (DDA) value that
   requires unescaping--for example, an at symbol (@), or an exclamation point
   (!), or an underscore (_), which are entered as (a), (b), or (u)
   respectively.

CAUSE
=====

The message transfer agent (MTA) will unescape the address but will also
unescape the parenthesis if it passes through an X.400 Connector to another
system that has the same address space (such as c=US;a= ;p=*;). The address 040
and 041 should be converted by the sending MTA before transmission.

RESOLUTION
==========

WORKAROUND
==========

The user can create a one-off address of

   X400:c=US;a= ;p=<organization>;o=<site>;s=Test with
   (a);dda\:EMS=TEST\@

or create a custom recipient in the global address list on the sending server.
The Address Book Provider (ABP) that processes the address in the message can
submit a Distinguished Name (DN) to the server in the P1 content and the
parenthesis are not converted.

STATUS
======

Microsoft has confirmed that this is a problem in Microsoft Exchange Server
version 5.5. This problem was first corrected in Exchange Server 5.5 Service
Pack 3.
