[QUOTE=mjt57;1489178]I have a number of MS Word documents (Word 2007) that I tried to convert to MOBI format to upload to my Kindle. However, Calibre doesn't recognise them. So I had to save them as RTF documents which Calibre then imported and converted for me.
Mobi has it's own converter, which works well for PRC docs and can convert from MS Word. I use it all the time for PRC or mobi format. You can then either open with an Mobi PC emulator or Kindle Content
