Possible solutions:
1. Make sure the recipient is trying to open the document with Word and not
something like OpenOffice or Notepad.
2. Find out what version of Word the recipient is using and make sure your
document is in a format compatible with that version. (Note that .doc can be
opened by pretty much any version of Word.)
3. Save the document in Rich Text Format (.rtf) and send that instead of
the Word document (.doc/.docx/.docm).
4. Convert the document to PDF and send that instead of the Word document.
5. Tell the recipient that it's not really a Word document at all, just a
huge game of tic-tac-toe. <g>
