34.2  Windows Calendar

Windows Calendar is a Microsoft Corporation's application used for calendar management on Windows Vista and higher. This 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 Windows Calendar. In addition to subscription to their own calendars, users can also subscribe to calendars shared by other users.

Warning

In Windows Calendar, 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).

Subscription traffic is performed by the HTTP or the HTTPS protocol. Publishing of calendars is performed via HTTPS only. This implies that it is necessary that the service is running in Kerio MailServer and a valid Kerio MailServer's SSL certificate must be installed on the Windows Calendar host. In addition to this, it is also necessary to map the corresponding port on the firewall protecting the server. Otherwise, the service will not be available from the Internet (for details, see section 2.3  Firewall configuration).

The Windows Calendar application supports iCalendar which is a standard format used for exchange of calendar data. The iCalendar built in Kerio MailServer enables Kerio MailServer to support cooperation with Windows Calendar.

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

Specific options and settings of Windows Calendar are focused in the Kerio MailServer 6, User's Guide).
