CalDAV and CardDAV are web protocols that use standard URLs for accessing remote resources, specifically Calendars, Tasks, and Contacts. When configuring access to these types of resources, the correct location needs to be provided via a URL string. If an attempt is made to access a resource that is shared (e.g. Public Folders), sufficient access rights have to be granted.
The URLs (paths) are most useful when configuring Apple Calendar and Contacts (Address Book) manually.
Folder sharing configured properly in Kerio Connect
Assumptions for the paths used in the URLs for this article:
mail.example.com represents the hostname of the Kerio Connect server.
example.com represents the email domain where the item is located.
user-name represents the login name of a user.
resource-name represents the name of a room or equipment.
The URL is meant to be used on a CalDAV/CardDAV client only. You cannot access the remote resources by going to the link directly in your web browser. You will receive 501 Not Implemented response.
The following URLs can be used to access Calendar, Contact, and Task folders via CalDAV and CardDAV protocols:
For user's own calendar and tasks:
For shared calendars and tasks:
For a specific resource calendar:
For public calendars and tasks:
When using Thunderbird versions 78.0 and later, the below URLs should be used:
For user's own calendar and tasks the URL should be
For Private calendars, the URL should be
For user's own contacts:
For shared contacts:
For public contacts:
The personal, shared or public Calendar or Contacts are synchronized correctly in the corresponding application. For example, public Contacts and Global Address Book in Apple Contacts.
