Exchange Server 5.5 or Exchange Server 2003 may return truncated message text if the CDO application is running as a service

When you run the Collaboration Data Objects (CDO) application as a Microsoft Windows NT service, if a message body contains double-byte character set (DBCS) characters, the Exchange Server information store may return a truncated message body.

When the CDO application runs as a Windows NT service, CDO uses Unicode text to get the message body. Because the message body is stored as American National Standards Institute (ANSI) text, the Exchange Server information store converts the ANSI text to Unicode text. This problem can occur during the conversation if a DBCS character spans the 16 kilobyte (KB) boundary.
