Most, if not all, of my users calendars have moved ahead one hour.
I am writing from Uruguay, where we were due to "fall back" from summer time
this past Sunday. However, the government decided to extend summer time two
more weeks, (i.e. instead of falling back on the 2nd Sunday of the month,
instead the 4th) so we sent out a registry edit to all of our user's pc's.
I am aware of KB886775 that talks about how to make the change specifically
for Uruguay. We followed that article and this is the result. We are using
Outlook 2003 and Exchange 2003. Our domain controllers have the correct
time and time zone information. Our Exchange 2003 server is on a domain
controller.
The result? Chaos. Some PC's changed time correctly. Some did not
(combination of registry security settings as well as the Microsoft
Antispyware tool being installed). When we got all of the users fixed,
their calendars are all off by an hour. If an appointment showed at 9am
before the change, it now shows at 10am.
Is there any utility that can change the base time of an outlook
appointment? Does the time zone on the exchange server have anything to do
with this (it is and was correct).
What are my options?
These are the registry edits that went out:
