The worst file corruption I ever had with a Word file was a file that originated on a fully up-to-date Word:Mac version that was completely hosed upon opening with a not fully up-to-date Word:Win. The solution? Take the original file, open it in LibreOffice/OpenOffice or Pages, re-save as .doc.
In my experience, using LibreOffice is much lower probability in FUBARring Word files than Word itself. The big problem is these godawful file formats Microsoft decided to employ that everyone and their mum uses to exchange files with. If you could only teach people to use some other format for sharing. For a long time, you could use the original Word file format, RTF. Except that the majority of users didn't understand how, why, when, what for.
