Outlook 2010 Calendar displays shifted meeting and appointments

Question

We use Exchange on 2003 SP2 and Outlook 2010 on the workstaions.
Some workstations are WinXP SP3 and some W7 SP1 (64bit and 32bit)
All appointment shifted to one hour later. That is if there was an apppointment which was 10:00 AM, it now shows as 11:00 AM
New meeting request show one hour ahead, that is if an appointment for 7:30 AM is sent, i see it as 6:30 AM.
The problem is we never have any such problem with Outlook 2007 and now, since we started to upgrade to Outlook 2010 it has started.
Even now - there ia no problem with WinXP! The problem is ONLY on Win7.
I checked we have no duplicate CDOEX and CDO dlls and even I re-registered both dlls.
It does not seem to help.
We work with DST disabled and it will not help!
The problem is mentioned a lot but I seem to be unable to find a usefull answer.
Regards,

Hi Marcel!
You should call in and open a support incident on this issue, as this issue is too involved to adequately work over a forum.
That being said. I don't know if the script could\would have caused this issue. Do you have a Win 7 with Office 2010 box that you haven't run the script on? Are you seeing the issue from a Win 7 box that hasn't had the keys\values set?
After checking out the keys\values the script sets and what they do, I'd then need to see a repro of the issue to make sure I understood exactly how the appointment was created and when the shift in time occurred.
To dump an item's properties, you can use MFCMapi to access the item in the Exchange folder and save off the properties. Or OutlookSpy to go in through IMessage on the item and save the properties off as a txt file.
At least you have the issue narrowed down to the Win 7\Outlook 2010 machines. Being that the situation you describe sounds like the machines are using the DST rules, I would begin by making sure that DST is definitely being disabled.
Go into Regedit: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
Add a new DWORD value with the name "DisableAutoDaylightTimeSet" --Set its value to "1". Which equates to "Disabled".
You can see more of an explanation of the setting here:

Marcel, I don't like asking people to open support tickets. The whole purpose of the forums is to learn\share information and to help resolve\figure out
what is happening.
Sadly, in a case like this where the results don't match what is being done, we're probably looking at something in the environment on the Win7\Outlook 2010 machine, something external (app, device, etc) modifying the item, or the application not respecting
the machine's DST settings.
Were I to get your issue: I would start by seeing how many and who is affected.
You've narrowed this to Win7 w/ Outlook 2010. Are all Win7\Outlook 2010 machines affected? --If the script is not run, and you set "DisableAutoDaylightTimeSet" to "1" manually, do you have the issue?
Does anyone on the machine have the issue? --Have a working user logon to the Win7\Outlook 2010 machine and configure an Outlook profile and see if the issue reproduces.
Is the affected user connecting to their Mailbox's Calendar from any other machines\clients? Devices? What about Delegates or people who have been granted access to their Calendar?
If all the settings are showing DST disabled, but Outlook still puts the Appointment an hour off then we would likely want to get an iDNA trace while the issue was reproduced. The iDNA would allow us to track all the calls\functions Outlook 2010 is making
up to and including the time shifting an hour off.
At this point, I literally have nothing else to add or share with you. Please call in and I assure you we will help you to resolve this issue.
Happy Easter to Everyone!
