Calendar appointments that are created on the BlackBerry smartphone set to an Australia Time Zone appear one hour earlier

Overview

Where BlackBerry® smartphones are set to AUS Eastern Standard Time or AUS Western Time Zone, and the BlackBerry Enterprise Server and Microsoft environments have been updated with the latest DST updates (referenced in KB19980), creating a calendar appointment on the BlackBerry smartphone or receiving a calendar appointment from a BlackBerry smartphone causes the appointment to appear in the Microsoft® Outlook® Web Access mailbox as one hour ahead of its intended time.

The appointment will appear for the correct time when it is created using Microsoft Outlook Web Access or Microsoft Outlook, both on the BlackBerry smartphone and in Microsoft Outlook Web Access.

Environment

  • BlackBerry® Enterprise Server 4.1 to 5.0

  • Microsoft® Exchange 2003 to 2010

  • SDR146875


Cause

When the BlackBerry Enterprise Server is installed, the registry information that is created for AUS Eastern Standard Time or AUS Western Standard Time does not include the correct time zone registry entry for Daylight Savings Time. As a result, when a calendar appointment is created on the BlackBerry smartphone, the BlackBerry Enterprise Server uses the time zone information within its current registry information and places the appointment one hour outside of the intended time.

Resolution



Warning: The following procedure involves modifying the computer registry. This can cause substantial damage to the Windows® operating system. Document and back up the registry entries before implementing any changes.

Important: Restarting certain BlackBerry Enterprise Server services delays email message delivery to BlackBerry smartphones. For more information, see KB04789.

For 64-bit Operating Systems:

1.    Stop all BlackBerry Enterprise Server services.

2.    Back up the registry on the BlackBerry Enterprise Server.

3.    Delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Research In Motion\BlackBerry Enterprise Server\Time Zones

4.    Import Update_for_CDO_(CDO VERSION 2003 or 2007) 64bit.reg from the Attachments section.

For 32-bit Operating Systems:

1.    Stop all BlackBerry Enterprise Server services.

2.    Back up the registry on the BlackBerry Enterprise Server.

3.    Delete HKEY_LOCAL_MACHINE\SOFTWARE \Research In Motion\BlackBerry Enterprise Server\Time Zones

4.    Import Update_for_CDO_(CDO VERSION 2003 or 2007).reg from the Attachments section.
