Tip - Accepting an iCal invitation - MSOutlook.info

I received a meeting invitation from someone but I cannot accept the meeting invitation as I can't use the Accept, Decline and Tentative buttons. I believe the sender used iCal on a Mac to send me this meeting request. Is there any way I can still accept this so it will go into my Outlook Calendar?
