It's based on the format of the message. Rich Text format messages show
the attachments in the message body while Plain Text & HTML mail messages
show the attachments in the header

Hi,
Attachment does not show on header which usually below cc field but it is
in message body when I create new email in outllook 2003 but another
outlook will attach in header on another machine. Any tips and
information will be appreciated.
