SYMPTOMS
In Microsoft Exchange 2000 Server, when you load an e-mail message from an electronic mail (.eml) file by using the IMessage::GetStream Collaboration Data Objects (CDO) function or the IBodypart::GetStream CDO function, the function may return a corrupted stream. For example, if you use either of these CDO functions to extract the contents of a Multipurpose Internet Mail Extension (MIME)-encoded e-mail message, the contents of a body part stream may be different from the contents of the original .eml message file. When you view the contents of the returned message, you may experience one or more of the following symptoms:
 * Some Unicode characters do not appear.
 * Some spaces are missing.
 * Extra carriage returns are added.
 * Text that identifies the message as MIME format is added.



CAUSE
This problem occurs because the character set of the ActiveX Data Objects (ADO) Stream object that is returned by the IBodypart::GetStream function or by the IMessage::GetStream function is set to UCS transformation format 8 (UTF-8) encoding. Therefore, the following specific problems occur:
 * The ADOStream::WriteToFile function adds a 3-byte UTF-8 format order mark at the beginning of the file. This order mark corrupts the first header property name in the MIME-encoded message.
 * The ADOStream::ReadFromFile function adds a 3-byte UTF-8 format order mark at the beginning of the MIME-encoded message. This order mark corrupts the first header property name that is obtained from CDO.



RESOLUTION
To resolve this problem, obtain the August 2004 Exchange 2000 Server Post-Service Pack 3 update rollup.
