Overview

The Calendar and Contacts Server (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.

Warning:
  • We removed this plugin in cPanel & WHM version 120. cPanel & WHM version 120 and later use the cpdavd service for calendars and contacts management.
  • This plugin does not support the CloudLinux™ 9, Rocky Linux™ 9, or AlmaLinux OS 9 operating systems.
  • This plugin requires PostgreSQL®. If you remove PostgreSQL, you will also remove CCS.
  • If your server resides on a NAT-configured network, it must support loopback NAT. CCS must be able to connect to the server’s public IP address.

Install the Calendar and Contacts Server plugin

To install the CCS plugin, perform the following steps:

  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.

Uninstall the Calendar and Contacts Server plugin

To uninstall the CCS plugin, perform the following steps:

  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.

Connect the Calendar and Contacts Server plugin to other devices

You can connect CCS to Roundcube or other applications. For more information, read our How to Set Up Calendars and Contacts and Calendar Delegation documentation. As a system administrator, you can also directly access CCS data through port 2080.

Z-Push - ActiveSync Support

We offer Exchange ActiveSync (EAS) support for CCS through the bundled Z-Push - ActiveSync Support plugin. Z-Push is an implementation of the EAS protocol. It allows synchronization of calendars, contacts, and email on Android™ devices. This additional plugin automatically installs when you install the CCS plugin. You will only see this plugin if you have installed CCS.

Once you install this plugin, your cPanel users can set up their calendars, contacts, and email on their Android devices using EAS. For more information, read our How to Sync Calendars, Contacts, and Email on Android™ Devices documentation.

The logs for the Z-Push - ActiveSync Support plugin rotate on a regular basis if they grow excessively large. For more information about Z-Push log files, read our The cPanel & WHM Log Files documentation.

If you do not need ActiveSync support for CCS, you can uninstall Z-Push while leaving CCS installed.

Warning:

We deprecated the Z-Push - ActiveSync Support plugin in cPanel & WHM version 118 and will remove it in a future release. For more information, read our cPanel Deprecation Plan documentation.
