Setting up Outlook.com on a Mac

Hi. Does any one know how to set up Outlook.com on a Mac? Ouutlook.com works ok on both the iphone and ipad but we can not get to send an email on the Mac. Any one have any ideas.
Thanks

I tried the 'free trial' but balked at the high cost of installation. Be aware of the costs to join.

You do mean Outook as an installation on your computer with Word and Excel as opposed to the confusing new Hotmail service called Outlook.com?

Thanks and yes I am talking about Outlook.com and not the Outlook program. I'm not sure what "free trial" you are referring too. If you are referring to Outlook.com, nothing I've seen so far indicates it's anything but a free service.
