Appointments are not displayed correctly in Outlook Mobile Access

When a user uses Outlook Mobile Access to view appointments, the appointments are not displayed correctly. The appointments are one hour ahead. Or, the appointments are one hour behind. This problem occurs if the following conditions are true:

• You apply the software update that is described in the following Microsoft Knowledge Base article:
  933360� August 2007 cumulative time zone update for Microsoft Windows operating systems
• The Tzmove.exe tool is used to update a mailbox of a user according to daylight saving time (DST) 2007 rules.
