Step by step run of the Exchange Calendar Update Configuration Tool (MSExTMZCFG.EXE)

We have applied all patches in the correct order, and everthing looked good at first. However now we have noticed that invitees to recurring appointments see the appointment differently, and that individual users see the appointment differently depending on if they view the appointment via Outlook, OWA, or their Blackberry.

Here is an example for a recurring appointment:
Organizer (desktop and calendar patched): sees appointment correctly from Outlook, OWA, and Blackberry
Attendee #1 (desktop and calendar patched): sees appointment 1-hr late in Outlook, 1-hr late in OWA, and correct from Blackberry
Attendee #2 (desktop and calendar patched): sees appointment correctly in Outlook, 1-hr late in OWA, and correct from Blackberry

To resolve the issue, all a user needs to do is open the series in Outlook and go to Actions - Recurrence. (There the appointment shows correctly! In other words, even though Outlook shows it as 3-4pm, opening the appointment lists it as 2-3pm.) Click OK on the Recurrence info, then re-save the appointment. Everything now appears fine, even though the user made no changes to the appointment. All the user has done is open the recurrence window and click OK.

Any help or advice would be greatly appreciated.
