Setting default font in Outlook

Hi guys, first post here but I've trawled the forums a few times before for help.

Basically I'm creating a logon script (a VBScript file) that, amongst other things, creates and assigns an e-mail signature with values from the user's AD account. This all works fine, but I can't seem to find a way to programatically set the default font for new e-mails and replies in Outlook.

I've searched no end of different sites on a few occasions, but with no result. It seems like something that should be really easy.

Any help would be greatly appreciated, as it's the last hurdle I need to overcome to get this thing finished off.
