Wireless calendar synchronization known issues
If a BlackBerry® device user creates a recurring appointment with the time duration set to 0, and then the user changes one of the instances on the BlackBerry device, the change is not synchronized to the email application and the device deletes the instance. (DT 1256362)
If a user creates a recurring meeting using Microsoft® Outlook® Web Access, the meeting is not synchronized to the device. (DT 1229655)
If the time zone on the device is set to GMT+10 Canberra, Sydney, and the BlackBerry® Enterprise Server uses CDO to connect to the calendars, when the user creates a recurring meeting on the device, the times on the device and email application might differ. (DT 1351936)
Workaround: Use the GMT+10 Hobert time zone on the device instead.
When using calendar web services in an environment that includes both Microsoft® Exchange 2007 and 2010, appointments might not synchronize to devices snf the log files might include the following message: "COM Exception: Code = 80131501 - Description = An internal server error occurred" (DT 1156803)
When a user creates a calendar appointment on a BlackBerry 9800 smartphone that includes Korean characters in the subject and location lines, after the device synchronizes the appointment with the BlackBerry Enterprise Server, the Korean characters show up incorrectly. (DT 1065593)
During calendar synchronization, if the BlackBerry Enterprise Server cannot determine the time zone for a calendar entry, the calendar synchronization process fails. (DT 1064478)
Workaround: Delete and recreate the calendar entry in Microsoft® Outlook® and run the calendar synchronization process again.
In some circumstances, if you disable wireless calendar updates and delete all calendar entries on a device using the BlackBerry® Web Desktop Manager, duplicate calendar entries might be created during a full synchronization process between the Microsoft Outlook calendar and on a device. (DT 995308)
Workaround: Manually delete the duplicate calendar entries in Microsoft Outlook Calendar and perform a second slow synchronization operation.
For certain BlackBerry® 6 devices, after a user receives a meeting invitation on a device, when the meeting organizer sends an update, the device displays the update as an email message and not as a calendar entry. (DT 891984)
If you configure the BlackBerry Enterprise Server to support Unicode characters, and a user receives a meeting invitation on a device, the meeting organizer's display name shows as the alias name. (DT 697329)
Workaround: Change the value of createCDOProfile to 0 and restart the BlackBerry Enterprise Server services.
