Calendar and Contacts Server (CCS)
Valid for versions 118 through the latest version
Last modified: March 15, 2024
Overview
The Calendar and Contacts Server (CCS) plugin allows cPanel users to manage their CalDAV (calendar) and CardDAV (contacts) accounts directly from the cPanel & WHM server. Once installed, CCS becomes the primary tool for calendar and contacts management.
Warnings:
- This plugin was removed in cPanel & WHM version 120. Versions 120+ use the cpdavd service instead.
- CCS does not support CloudLinux™ 9, Rocky Linux™ 9, or AlmaLinux OS 9.
- CCS requires PostgreSQL®. Removing PostgreSQL removes CCS.
- Servers on NAT networks must support loopback NAT so CCS can connect to the server’s public IP.
Install the CCS Plugin
- Navigate to WHM » Home » cPanel » Manage Plugins.
- Click Install “Calendar and Contacts Server”.
Uninstall the CCS Plugin
- Navigate to WHM » Home » cPanel » Manage Plugins.
- Click Uninstall “Calendar and Contacts Server”.
Connect CCS to Other Devices
You can connect CCS to Roundcube or other applications. Administrators can also access CCS data directly via port 2080. For setup instructions, refer to the How to Set Up Calendars and Contacts and Calendar Delegation documentation.
Z-Push – ActiveSync Support
Z-Push provides Exchange ActiveSync (EAS) support for CCS, enabling synchronization of calendars, contacts, and email on Android™ devices. This plugin installs automatically when CCS is installed.
Important Notes:
- You will only see this plugin if CCS is installed.
- It was deprecated in version 118 and will be removed in a future release.
- It requires at least 7 GB RAM and 4 CPU cores.
