Overview

In cPanel & WHM version 80, we introduced the Calendar and Contacts Server (CCS) plugin. The CCS plugin allows your cPanel users to manage their CalDAV (calendar) and CardDAV (contacts) accounts from your cPanel & WHM server.

When you install this plugin, CCS becomes the main calendar and contacts tool. Your server keeps the information available in Horde. However, cPanel account and Webmail users can no longer connect to the Horde calendar or address book.

Warning:

  • The CCS plugin is EXPERIMENTAL. This plugin is unstable and can result in unintended consequences. Exercise caution when you enable this plugin. This feature's behavior may change in a future version.
  • This plugin is compatible with CentOS 7, CloudLinux 7, and Red Hat® Enterprise Linux® 7. This plugin is not compatible with CentOS 6, CloudLinux 6, Red Hat® Enterprise Linux® 6, and Amazon Linux.

Install the plugin

To install the CCS plugin:

  1. Navigate to WHM's Manage Plugins interface (WHM >> Home >> cPanel >> Manage Plugins).
  2. Click Install "Calendar and Contacts Server". A success message will appear when the installation process completes.

Your cPanel users can now connect CCS to Roundcube, Horde, or other applications. For more information, read our How to Set Up Calendars and Contacts documentation. Enter port 8443 when you set up the server name and port.

Note:

As a system administrator, you can only access CCS data through the calendar port (8443). You can manage CCS data through Horde, Roundcube, or other applications.

Uninstall the plugin

To uninstall the CCS plugin:

  1. Navigate to WHM's Manage Plugins interface (WHM >> Home >> cPanel >> Manage Plugins).
  2. Click Uninstall "Calendar and Contacts Server". A success message will appear when the uninstallation process completes.

Warning:

The system erases all CCS data when you uninstall this plugin.
