Just wondering, how to, or is there a way, to set up an Office 365 (Exchange) Calendar (account) in Mountain Lion's Calendar app? (formerly iCal)

The reason being, I don't always launch Outlook 2011 every time I am on my home iMac, but I would still like to view my office calendar somewhere, like on the Calendar app in Mountain Lion, from time to time.

I have successfully set up my Office 365 Exchange account (same account) on both iPad and iPhone.  But doesn't seem to be working on the Mac.

Thanks and cheers
