David, just for your info, we have noticed something similar with an exchange
2003 server and outlook 2003 clients.

The current thinking is that the 'hotfix' that was applied last year has
'dissapeared' and not been incorporated into a patch. We are investigating
down this path now.

Anybody else with similar issues?

We have just started seeing a problem in New Zealand with Daylight saving and
outlook calendar appointments.

Last year we applied all server, and exchange patches to our clinets and all
workstation and sharepoint patches. After we applied the pacthes all
problems went away. During fall of this year (March April for New Zealand)
when daylight saving ended there were absolutely NO problems.

Suddenly this week appointments between organizations we patched are 1 hour
out. When our customer makes an appointment with us it arrives 1 hour late.
When we accept they see us as TWO hours out.

OWA to outlook, Outlook to OWA, and OWA and OWA is fine - no problems.
Just when is goes through two outlook (one is 2003 and one is 2007) clients
does the error occur.
