Developed by Apple Computer, Apple iCal is an application allowing management of calendars on Mac OS X. The application enables to view events of multiple calendars in a single schedule and thus quickly identify conflicts in the time schedule.

Calendars may be either stored on the disk or it is possible to subscribe for calendars stored at the web server. It is also possible to publish calendars on the web server.

Kerio MailServer supports publishing of calendars in user email accounts on the server and subscription of calendars stored in the mailbox from the Apple iCal. In addition to subscription to their own calendars, users can also subscribe to calendars shared by other users.

Warning: In Apple iCal, subscribed calendars are available only in the read-only mode. Published calendars are available on the server for reading only (this implies that it is not edit published calendars when accessed by Kerio WebMail, for example).

Notes: If calendars published as subfolders of the default calendar called Calendar, all events will also be displayed in the Free/Busy calendar.

Apple iCal is also supported by Kerio Sync Connector for Mac, a special utility allowing direct synchronization of calendars and their contents with calendars in Kerio MailServer (for details, see chapter 13  Kerio Sync Connector for Mac ). This application is recommended especially for Mac OS 10.4 Tiger hosts.

Apple iCal supports CalDAV since Mac OS 10.5 Leopard. Once a CalDAV account is set, it is possible to synchronize calendars over CalDAV. For details on the CalDAV protocol and Apple iCal configuration, read section 11.5  CalDAV support.
