We have recently installed an Exchange Server 2010 and deployed Office 2010 including Outlook 2010. The CEO wants to chnage the default font from Arial 10 pt for all staff but I can't find a way to make it work. I can change the settings in the Outlook client (say to Calibri 12 pt) but every time the users logs out and back in again the default font has changed back to Arial 10 pt. Has anyone found where to set the default font for all users on the network?
