Support for Apple Mail in Exchange accounts results in displaying of all calendar folders included in a particular user account in Kerio MailServer. Apple Mail does not support the calendar view mode and therefore each event is displayed as one email message. Such messages include an .ics attachment with all data associated with the corresponding event.
Thus, each event can be simply imported to Apple iCal (for details, see chapter 10 Apple iCal Support) where it can be displayed easily.
Another benefit of the settings is that all types of public folders can be viewed in the account. The following folder types are displayed:
contacts
calendar
tasks
notes
Apple Mail displays all types of public folders since their download is always performed via the IMAP protocol.
