They can subscribe to external calendars and view their calendar information from Zimbra Web Client. They can also use search for appointments in their calendars.

Features

Group Calendar

When Group Calendar is not checked, users can create personal appointments and accept invitations to meetings only. The Find Attendees, Schedule and Find Resources tabs are not displayed.

Features

Nested Calendars

Calendars can be nested within ZCS folders like Mail, Contact, and Calendar folders. The administrator creates a nested list of calendars using CLI. A nested calendar grouping can be imported through migration as well.

The CLI command to define the grouping is

zmmailbox -z -m user1 cf -V appointment /<Calendar Name>/<sub-calendar name>.

This creates a calendar nested under the Calendar Name folder.

Timezone

Sets the timezone to use for Calendar scheduling. Domain admins set this in the Accounts, General Information page.

Preferences

Forward calendar invitation to specific addresses

You can specify email addresses to forward a user’s calendar invitations. Users can also specify forwarding address from the Preferences Calendar folder.

The account the invitation is forwarded to must have admin privileges on the shared calendar to reply to the invitation.

Accounts Forwarding

The CLI zmcalchk command is used to check for discrepancy between different users’ calendars for the same meeting and send an email notification regarding the discrepancies.

You can also use this command to notify the organizer and/or all attendees when an appointment is out of sync.

Remote calendars are updated every 12 hours by default. You can change the frequency of these updates in the administration console Class of Service or Account Advanced page, Data Source>Calendar polling interval.

Attendees can edit appointments in their calendars, but the changes do not affect anyone else, unless the user is the appointment organizer. If the organizer makes changes, these changes overwrite the attendees edits. You can not allow attendees to edit appointments in their calendars from the COS attribute, zimbraPrefCalendarApptAllowAtendeeEdit.

zmprov mc <cosname> zimbraPrefCalendarApptAllowAtendeeEdit= FALSE
