Where does Microsoft Office 2008 install fonts? Do I need to keep them there, or can I manage them with FontAgent Pro?

Office 2008 places it's fonts on install in the /Library /Fonts/Microsoft/ folder. None of the fonts are required for Office to run, so you can remove these fonts from that location and import them into FontAgent Pro. If you are a power user of the Office 2008 suite of applications you may want to import them into their own library for easy management.

Otherwise, you can set FontAgent Pro to manage your system fonts in the Preferences Pane and the fonts will be added to the System Fonts (Library) library.
