OwnCloud includes a lot of other services such as shared contacts, integration with external cloud storage vendors such as Amazon, Dropbox and Google, and integration with internal storage servers and devices.

Its most developed features are file sharing and synchronization, and calendaring. These are essential tools for most small businesses, so we’ll look at how to use OwnCloud for these services.
