Additional information about Exchange and Daylight Saving Time 2007 is now available

Hello,

So if I am to read this correctly, all Exchange installations will have to patch the Server's operating system, Exchange itself (also to cover Entourage) and probably all workstation's operating systems and Outlook (if not 2007) to resolve this issue?

regards,
Larry

So, what do we do if we are still running Exchange 2000 and don't have Extended support?

We are waiting for the Outlook Data Update Tool since none of our workstations have Outlook 2007.  

We wish it had been released before now since we have release management requirements ... some sites which only allow changes once per month.

We will be hard pressed to get the patches out for our users since the tool has not been released.

Thanks,
Exchange2003

We wish it had been released before now too.  We schedule meetings months in advance and our calendars are all off during those initial 3 weeks.  Geez, this change has been known for a year and a half.  And no, we can't upgrade from E2K before March 11.  Thanks, Microsoft.

if appointments are already scheduled for those dates, and the OS and Exchange are not yet updated, will updating the Exchange and OS be enough? or should be update outlook as well ?

btw, we have been having DST issues for 5 years in israel , since DST is change every year.. join the club :)

The new information posted at the "Preparing for Daylights Savings Time changes for 2007" has rasied more questions than answers.  In a large corporation, there is a great possibility that there will be calendar entries made that will incorrect after all the patching and tools have been applied.
Before the OS is patched on the workstation, Outlook will store appointments in the Exchange database without he new GMT offset.  When the workstation OS is patched, Outlook will begin to store the appointments in the Exchange database in GMT using the corrected offset for the new DST.   This means that all workstations need to be patched before the Exchange tool can be re to "fix" the old appointmnets.  Even with SMS, it takes about 5 days for the patch to be applied.  That means there will be some appoints stored correctly while others will be incorrect.  If you then run the Exchange tool, it will change the time on all appointments from 3/11 - 4/1, thus incorrectly changing those that had the corrected time.  This gets worse when you include, Blackberry devices, Mobile devices, home workstations and Public Folders and applications that use CDO. What solution does MS offer to reduce the risk of incorrectly changing appointments?

Thanks

I think there's a lot of confusion going on overall.  I was in a conference call with Microsoft TAM and he thinks that there'll be a webcast to go over Exchange and Outlook to get the DST changes.  Just to be clear, there are no patches for Outlook client, but there'll be tools to fix appointments, Outlook Data Tool, against calendars in mailboxes.  This tool will be available in standalone and enterprise.

Addressing daylight saving time using the Outlook Time Zone Data Update Tool

Here's what I'm contemplating with my Exchange 2000/Outlook 2002 environment:
- Update Exchange server OS time zone data via TZEdit.exe
- Apply timezone update to all client OSs (XP SP2) via WSUS
- Run Exchange Timezone update tool against all Exchange mailboxes

My questions are:
-Will the soon-to-be released Exchange Timezone update tool work with Exchange 2000?
-Given that I will not have updated CDO on the Exchange 2000 server, I expect OWA (running on that same Exchange 2000 server) to have DST issues, but what about patched Outlook 2002 clients? Will they be OK?

Thanks

Jack

  Your plan above will work.  There will be OWA issues during the delta period where appointments made with OWA and viewed with OWA will be one hour off.  the Exchange tool will work against all versions of Exchange.  it does require Outlook 2003 our Outlook

2007 to run.  if you don't have Outlook 2003 or Outlook 2007 you can use the trial version that is located here:  http://www.microsoft.com/products/info/product.aspx?view=22&pcid=04ea691a-7698-417d-bf3b-2d1ce6cce13a&crumb=catpage&catid=9d273393-92c9-4807-be9c-515a0d152415

There will be a webcast on Feb 2.  I don't have all the details at the moment but will post them when i do.  this webcast is externally facing and is intended for customers and partners.

FYI - The Exchange DST Daylight Savings Time patch killed one of our database servers.  Kept giving us an error, so I had to go in and find the patch folder under C:Windows - and run the spuninst.exe file located in there to remove the patch.  Reboot and your databases will mount again.  I guess until March, I just have to keep my eyes out to see what MS says about it.  Hopefully try that patch again later.
