This problem may occur when the following conditions are true:
The default MIME encoding in Exchange Server 2003 is 7-bit transfer encoding. The MIME encoding in some Asian languages must be set to an encoding method that is different from 7-bit encoding. The lines of text that contain more than 998 characters can then be wrapped.
