Microsoft Office 365 is a subscription service that provides access to Microsoft Office applications and other productivity services over the internet. It comes in several plan options for both business and personal use at different price points. The plans vary in features included, such as whether they provide online-only access or include installation of Office applications on devices. Office 365 generally provides the best experience when using the newest versions of Office. It can be used as either a cloud-based or hybrid solution working with existing on-premise Exchange servers. An alternative to Office 365 is purchasing and hosting email and other services locally, but for non-profits Office 365 often provides the most cost-effective solution.
