Please note that this tutorial is a general guide. The CalDAV server on your host may require different settings. If the steps described below don't work for you, please contact your host's or company's tech support and ask them what settings you should use.
The first step in setting up any third-party app to work with the Roundcube calendar is creating a CalDAV connection. If you haven't done it yet, this tutorial will guide you through the necessary steps.
Click the arrow next to the New button and select Calendar.
Set Type to CalDAV and choose a name for the calendar. In the fields User and URL type the user name and the URL that you where given when you created the CalDAV connection in Roundcube (use the URL, not the Alternate URL.) Click Find Calendars.
When you click Find Calendars, an authentication dialog will be shown. Type the password you chose for your CalDAV connection in Roundcube.
In the calendar selection dialog, choose your Roundcube calendar and click Apply. Click OK to close the New Calendar dialog.
You should now see your Roundcube calendar in the calendar list on the sidebar and its events in the calendar grid.
