Calendar Email Address

I have a web page that once you click on a link, it will add an event to their default calendar using vCalendar.

I need this to populate a Shared SharePoint Calendar instead.  I have read where you can email a calendar email address and it will put the event on the calendar.  I cannot find where to enable in-coming email to the calendar.

If this can be done, when someone's leave is approved, I could have it automatically populate a department's calendar in sharepoint for the start and end date, etc.

Thanks in Advance,
