Microsoft Office 365 (often called Microsoft 365 or Office 365) is a Web-based version of Microsoft’s Office suite of enterprise-grade productivity applications. Office 365 is delivered to users through the cloud and includes Exchange Online for email, SharePoint Online for collaboration, Lync Online for unified communications, and a suite of Office Web Apps, Web-based versions of the traditional Microsoft Office suite of applications.

Microsoft 365 is part of Microsoft’s Software Plus Services strategy, combining the advantages of cloud-based remote computing software options with the company’s traditional base of on-premises software offerings. One advantage of Office 365 is that it is regularly updated approximately every 90 days and users are not required to pay upgrade fees.

Microsoft Office 365 is available in several plans to suit your business needs, ranging from $5.10 user/month (Business Essentials) up to $23.20 user/month (Enterprise E3). Pricing is based on an annual commitment. Standard Office subscriptions are also available for home, student, government and nonprofit users.
