Outlook/Exchange 2003 - Random appointments times changed

[pengo]

Recently, staff at my work have noticed that some of their appointments in Outlook have their times changed.

They are either 1 hr earlier or late or even the date has changed to the next day - the time is right but its set to finish on the next day. So it results in a 2 day appointment.

For example, one appointment should be:

Start - 20/10/08 11am

Finish - 20/10/08 12pm

but is now:

Start - 20/10/08 11am

Finish 21/10/08 12pm

This is happening across more than one mailbox so I've ruled out that appointments have just been updated and staff haven't been told.

We had the problem with appointments in a public folder being out by an hour. We fixed this by running the Outlook Timezone mover tool. As I suspect this is to do with the DST update for 2008. Running the tool does not fix the problem on the personal mailboxes.

Has anyone else come across some of the problems I've mentioned? What did you do to fix it?

Thanks
