Whenever I give someone a .odt file created with LibreOffice and they open it with Microsoft Word, it says that the file is corrupt. Is there a CRLF problem or are the .odt files MS Word makes and the .odt files LibreOffice makes different altogether?

I'm trying to promote using .odt files (there's an xkcd comic on this :P) but it seems as though Microsoft doesn't want that to happen. Is there a way to make sure that my .odt files will not appear corrupt to Microsoft Word?
