Different with Outlook 2013, after changing the font of calendar appointment, the whole calendar is changed together to the font you specified, such as the day number and so on.But at an absolute minimum, you should at least just be able to select a different calendar to show (rather than be limited to whichever default calendar Outlook has chosen)!! Showing multiple calendars in the one 'peek' view would be fantastic! (Or even just being able to scroll through your different calendars in peek view).
