Re: Exchange Time Zone Update Tool Run Before WKS patch

I thank you very much for all your help on this... I finally figured out the
problem.

I wanted to warn others only to reference the Microsoft DST site for
patches. There is a lot of misleading info out there - my issue ended up
being that we were using KB884020 as the XP patch which is NOT the correct
patch - that's why all my calendar items were off - the patch I thought was
correct was not. After I applied the correct patch- everything updated as
should have been....

Unfortunately, I did just as you had mentioned. The workstation that I
ran
the Exchange Update tool from was already patched -so i thought that the
mailboxes would have been baselined according to this workstation.

When I look at my mailbox on a workstation that wasn't patched, my appts
are
off. When I look at my mailbox on a workstation that was patched, my
appt's
are correct. This is why i'm leaning to believe that it is somehow
workstation specific with a tie in to Office...

Thanks again

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!!!
