Microsoft has released Office 2016 for both Windows and Mac. If you are an Office 365 subscriber then you can download this version. You can read a review of it here and here. I will admit that I am still using the 2011 version. I am not a heavy duty user of Office and see no reason to pay to upgrade. If I used Outlook then I would consider the upgrade and probably subscribe to Office 365 in order to have the latest, most secure version.
