Enterprise Email (Hosted In Cloud)
Office 365 is Microsoft’s cloud-based online business application subscription service that comes in two packages: One for enterprises with 25 employees but can go as far as 50 users, the other for enterprise users that can be scaled to as many seats as necessary.
While there are a number of differences between the two, they are fundamentally the same, offering Office Web Apps, Exchange Online, SharePoint Online and Lync Online, plus an external Web site to subscribers. For enterprises there is the additional option of upgrading to the beta of Office Professional Plus, which, Microsoft says, offers all the office software you could possibly want and more.
