Re: Exchange Time Zone Update Tool Run Before WKS patch

Tech-Archive recommends: Fix windows errors by optimizing your registry

It's important to understand how time works.
- Most time-related stuff, including NTP servers, use Coordinated Universal
Time (UTC).
- Windows operating systems have time zone definitions in the registry,
including the timezone you're currently in (this is what you selected when
installing the OS - e.g. Pacific Time (GMT -8:00).
- When you create appointments in Outlook, they're created using the current
time zone rules from your OS (which gets it from the registry). If you
create the appointment using old DST 2006 rules, and then update your
computer with DST 2007, the old appointments will appear an hour late.
- When rebasing appointments on the client side with the Outlook Calendar
Update Tool, you need to install the client OS time zone update first (KB
931836 for Windows XP SP2, and also for Windows Server OSes). Else, nothing
gets picked up or rebased.
- When rebasing appointments using the Exchange Calendar Update Tool, the OS
on the computer that you're running the tool from should have the Feb. 2007
Cumulative Timezone Update (KB 931836).

In either case, you should update all client computers with KB 931836
*before* you rebase appointments.
What happens if you don't do this? They can still create new appointments
using the old DST 2006 time zone rules.

Thank you for the quick reply!

Here is what I am noticing - for all mailboxes (the Exchange Calendar
Update
tool was run) - if a workstation was successfully patched, it looks fine,
if
the workstation was not patched logging on as the same user-it's an hour
off
- if the patch is applied afterwards, it is still off.

What is the link between the workstation patch and Outlook?

I have uninstalled/reinstalled the profile as well as Outlook to no
avail..next i will try the entire office suite..

Once the appointments have been rebased by either tool (Outlook/Exchange
Calendar Update), they will not get rebased again by running either tool.
It's likely you'll have to manually move appointments.

Hi All,

I have an issue where we ran the DST update on all servers, the CDO
update
on Exchange, and were in the process of running the wks updates (xp
sp2).
After waiting awhile, as I thought the wks updates were running
sucessfully,
I began running the Exchange TZUpdate tool from a wks that had been
patched
and had the proper permissions. Everything looked fine in the output
log.
Unfortunately, my wks updates failed on a good portion of my wks, so
now
my
users have appt's that are 1 hour off..strangely enough, some are not
even
within the DST adjusted weeks of 3/11-4/1 - probably because they are
recurring (?)

If I rerun either TZMove on each workstation or the EXchange TZUpdate
tool
after all wks's have been patched, will their calendar appt's be
updated
or
am I stuck having all my users change the appt's in question manually?

Thanks in advance!!!
