Changing Default Message Font in OWA for All Users

Hello,

is it possible in Exchange 2010/2013 to change Default font for new Messages in OWA for all users at once instead of having the users change the font manually through the UI.

I only found answer to Exchange 2007 where the answer was no, but wondered if this had changed in 2010 or 2013.

Thank you

Sascha
