I know this is far fetched, but just try it.
It worked for my buddy who has a company issued mogul, I thought it was a restriction put in place by the company, but it is in fact a bug in Word.

1) soft reset device
2) Start / Office Mobile / Word
3) Create a new document (click on New)
4) type some text (just plain text - no formatting - it was 'plain text document') just a few characters
5) File / Save As...
6) I have selected type 'Plain Text'
7) It asked me whether I want to save it at 'Word document instead' - I clicked No.
I have powered off the device and did soft reset
9) Start file explorer, find the file (it was in My Device / My Documents), click on it - it opens Word again.
10) Add some formatting (I have selected part of text and changed font to bold)
11) Close Word - it asked whether to save it in Word format - this time I said Yes
12) Power-off the device and press soft reset again
