TITLE   :XADM: Event ID 1026: Invalid Argument in MTSID
PRODUCT :Microsoft Exchange
PROD/VER:WINDOWS:4.0,5.0,5.5
OPER/SYS:
KEYWORDS:

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

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When sending e-mail to an Exchange Server recipient through a gateway, your
message may not be delivered, and the non-delivery report (NDR) indicates that
one or more arguments in the recipient was detected as being invalid. The
Microsoft Exchange Server information store generates the following application
event:

   Event ID: 1026
   Source:   MS ExchangeIS Private
   Category: Transport General

   An error occurred with the following call stack:
   EcTferOutMessage():  0080070057
   EcCreateOMTferOut():  0080070057
   EcMTSIDFromSz():  0080070057

CAUSE
=====

The Exchange Server information store returns an NDR for messages whose
PR_MESSAGE_SUBMISSION_ID (MTSID) contain a slash (/), semi-colon (;), or
quotation marks (") in the MTSID parts.

WORKAROUND
==========

Connectors passing messages into Exchange Server should not use the slash,
semi-colon, or quotation mark in the MTSID parts.

MORE INFORMATION
================

Other than the delimiters the information store uses between parts of the MTSID,
the format follows X.400 rules. An MTSID contains four parts:

    Part Name   Stringized form      CharSet      Max Length
    Country           C=             PRINTABLE        3
    Admd              A=             PRINTABLE       16
    Prmd              P=             PRINTABLE       16
    LocalIdentifier   L=             IA5             32

The information store simply parses the Stringized form and separates individual
parts according to the delimiters (; or /). For information about character
sets, refer to the X.400 specifications.

The Stringized form can enclose the parts in quotation marks if the part contains
a delimiter character. The information store correctly parses this, and
generates the correct om_object for MTSID. However, when the information store
gets an MTSID om_object from the message transfer agent (MTA), it does not check
to see whether the part contains a delimiter and therefor, encloses it within
quotation marks. So, quotation marks should not be used in the parts either.

Normally the part headers (C, A, P, and L) are not case-sensitive. However, if
the part header is capital L for LocalIdentifier, then PRINTABLE is assigned as
the CharSet instead of IA5 (IA5 is the correct one to use). So, in order to
guarantee correct behavior, you should use small "l" for the LocalIdentifier
header.
