This issue occurs because Outlook Time Zone Data Update Tool 2.0 and earlier versions do not support time zone definitions that change partway through a particular year.
Outlook Time Zone Data Update Tool 3.0 partly addresses this issue. In Outlook Time Zone Data Update Tool 3.0, all calendar items that have time zone properties stamped on them are rebased correctly.
