Nextcloud Contacts

Keep your relations organized

  • Share your address books with your team

User-defined group management

In Contacts, users can define their own, custom groups, named Circles. These can be managed in various ways, including with invitations, through an open listing where users can join with or without an approval step, with designated sub-managers and so on.

Users can share with these groups the same way as administrator-defined Nextcloud groups. Users can add members of a circle to a conversation, share a folder to a circle, assign a task to a circle and so on.

Integrated groupware, chat and project management

Nextcloud features tightly integrated chat, project management, mail, calendaring and more. Chat messages can be directly transformed into tasks, task deadlines are visible in the Calendar and files can be attached to a task from the sharing dialog.

A single platform means there is no need to juggle different accounts, keep track of where in the many cloud platforms the latest version of a document is floating around, or worry about security threats and invisible costs.

Benefits of a single platform

Nextcloud fluently integrates into your existing infrastructure while also providing its own. Note that Nextcloud Mail is a client for IMAP-infrastructure; Nextcloud does not include a mail server.
