TITLE   :XFOR: Cc: Field Moved to To: Field with MHS Extended Addressing
PRODUCT :Microsoft Exchange
PROD/VER:WinNT:5.0,5.5
OPER/SYS:
KEYWORDS:exc55sp2fix

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

 - Microsoft Exchange Server, versions 5.0, 5.5

SYMPTOMS
========

When a message is sent using the message handling system (MHS) Extended
Addressing format, the address specified on the Cc: field is moved to the To:
field.

The problem only occurs when MHS Extended Addressing style is used; for example,
user@host {<e-mail type>:<e-mail address>}; that is, user@host
{CCMAIL:test,user}. If another style of addressing is used, the problem does not
occur; for example, [mhs:user@gtwy{net/po/user}].
