I had the same problem. When I would send an all day appointment to a user,
they would receive it, however, their time was 3 hours ahead. I also checked
our time zone and they matched. Then, I opened up Outlook Options,
ToolsOptions, and clicked the Calendar Options button. I discovered their
calendar work week was Monday through Friday, while my calendar work week was
Sunday through Saturday. Once I changed that, it seemed to work fine.

I am having a problem with a client that sends out meeting notices via
outlook. When the notice is recieved by my computer, it is one hour earlier
than everyone else. I am using Outlook 2003. I have PST checked on outlook
with daylight savings time enacted. Out of the ten firms involved in these
meetings, two of our firms are having this same issue. I must stress we both
are using daylight savings time correction so this is not the problem
