[MS Word Spell Checker] data ?

I'd like to know the file which SDL refers for its "MS Word Spell Checker"

It is quite clear (from my side) that MS Word refers to this one;

But, it is quite different from SDL's spell checking status.


Is there any option(s) that SDL assumpts implicitly for this functionality ?

- SDL Trados Studio 2017
- MS Office 2013, 32Bit
- Win 8.1, 64Bit
