What may cause Calendar entries to not synchronize with the email client?
Calendar entries are saved to the base system calendar of a BlackBerry smartphone that is not activated on a BlackBerry® Enterprise Server. Entries in the base system calendar are only recognized by the Calendar application on the BlackBerry smartphone. Any external application will not recognize the Calendar entries. Note: The Number of Entries field in the BlackBerry smartphone Calendar option shows the number of entries in the calendar on the BlackBerry Enterprise Server. Because of the problem with wired synchronization, regardless of the number of Calendar entries on the BlackBerry smartphone, the value of the Number of Entries field in the Calendar options will always be 0.
