Outlook 2000:

SUPPORT SOLUTION:
Microsoft Office Outlook Time Zone Data Update Tool 2.0 and
earlier versions of this tool do not correctly rebase any calendar item that was created in
the Brasilia time zone. .Because of limitations in Outlook Time Zone Data Update Tool 2.0 and
earlier versions,
rebasing for the Brasilia time zone is not supported. 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. However, items
that do not have time zone properties stamped on them may be rebased
incorrectly. By using the appropriate command line argument,
you can disable unstamped items. For more information, click the following
