Office 365 has a new sales hook. Indeed, Microsoft (NASDAQ: MSFT) is making a special Cloud Easy offer to US partners that promote Office 365, Windows Intune and/or Microsoft Dynamics CRM Online. The Cloud Easy promotion, which runs July 1 through Sept. 30, 2012, offers special incentives to cloud customers and their channel partners.

At first glance, the Cloud Easy offer is designed mainly for cloud customers. But take a closer look and you'll see the program offers "money back on all Microsoft products to use towards future purchases, all through your Microsoft partner."

How much can customers save -- and potentially apply to additional purchases through partners? This Cloud Easy Calculator offers some answers.
