Microsoft Online Services is a set of Microsoft hosted messaging and collaboration solutions including Microsoft Exchange Online, Microsoft SharePoint Online, Microsoft Office Live Meeting, and Microsoft Office Communications Online. These solutions are available separately or as a suite - Microsoft Business Productivity Online Suite (BPOS).

These online services are designed to give your business streamlined communication with high availability, comprehensive security, and simplified IT management.

Because Microsoft hosts the services, it reduces your company's need to maintain IT services on site. Many organisations today are moving to this "software-plus-services" model, because it decreases the need to manage hardware and software.
