When a wired synchronization is performed, calendar entries created on the BlackBerry smartphone are not transferred to the email application on the computer. Also, any calendar entries created in the email application are transferred to the BlackBerry smartphone, even if they already exist there. As a result, duplicate calendar entries are created on the BlackBerry smartphone and the BlackBerry smartphone user's calendar entries in the email application might be removed.
This issue does not affect BlackBerry smartphones that are associated with a BlackBerry® Enterprise Server.
When a BlackBerry smartphone contains a compressed ICAL (CICAL) service book (as provided by a BlackBerry Enterprise Server or by a BlackBerry® Internet Service integration), calendar entries are stored on the BlackBerry smartphone in the service calendar. The value in the Number of Entries field in the calendar options represents the data stored in the service calendar.
When a CICAL service book is not present on a BlackBerry smartphone, all calendar entries are stored on the BlackBerry smartphone in the base system calendar. Calendar entries stored in the base system calendar are only recognized by the calendar application on the BlackBerry smartphone. Therefore, any external application (the Backup and Restore tool, Intellisync®, etc.) does not recognize the calendar entries.
