Office 2011 users have had to go without the instant e-mail delivery that Windows Office users have always enjoyed. Probably the most significant feature added in the new version is true push support for receiving Exchange e-mail. If you are a O365 subscriber and have the right licensing, you should be able to download the new version of Outlook immediately. Additionally, MSDN subscribers do not appear to be able to download the application through the MSDN software library (I have an MSDN subscription, and the new Mac Office is definitely not in my download library). More confusing, not all subscriptions are eligible (more on that in a minute).

At least for now, it’s subscription-only. This holds with Microsoft’s new policy of 'prioritiz mobile first and cloud first scenarios,' and it means that at least for now, users who don’t pay for monthly Office 365 subscriptions and prefer to buy 'perpetual' licensed versions (in other words, users who prefer to buy Office the traditional way) will have to wait at least until the first half of 2015 to get their hands on the new version of Outlook. There’s a caveat, though: the new version of Outlook for Mac can only be used if you have certain Office 365 subscriptions.
