I don't know what FOSS is, but Exchange doesn't have any iCal publishing features.
FWIW, the next version of Outlook will have substantial iCalendar subscription and sharing support.

I use a FOSS calendaring system, while the rest of my office uses Outlook.
Can I publish my .iCal file to our exchange server?
