Hi Thomas,
Not really, there isn't a single setting for that. Each app has its own method for defining default styles and the fonts that go
with them, and there are settings for each of these. You haven't mentioned the version of Office you're using. You may want to
have a look at the Office Resource Kit (ORK) for the version you're planning to deploy.

Default Font for the the whole office products:
if a users writes a mail, creates a powerpoint, excel etc, the font
arial should be preselected, thats all. >>
