I am migrating mailboxes from an Exchange 5.5 org to 2003. We have a script
that logs into a migrating user's mailbox and adds an appointment during the
users migration time with a reminder that will pop up about 6 hours ahead of
the migration. e.g we create an appointment on the calendar with a start time
of 7pm and end time of 11pm.

The worksation we use to create the appointment is in the Eastern Timezone.
The mailboxes were adding the appointment to are in the Pacific Time zone.
From the "eastern" workstation we log directly into the mailbox on the
pacific server, access the calendar folder, and add a new appointment,
logout, login into the next user, repeat. We set the .StartTime by setting
..StartTime = "11/15/2006 19:00:00" for example. On most of the mailboxes the
appointment shows on the users calendar as 7pm (when viewed from the user's
workstation which has the time zone set to Pacific) On some users calendars
the appointment gets added, but when viewed by a user in the pacific timezone
it shows 4pm instead of 7pm.

Based on what I know about outlook converting the time to GMT I would expect
the later to happen on all of the users because the appointment was created
on a workstation in the Eastern time zone.

Both of these users are on the same Exchange 5.5 server. The users and the
Exchange server are all in the same timezone (Pacific). Timezone settings in
the user's outlook options show pacific as the timezone.

Any idea why these are showing different for different users. The
appointments are all added by the same run ofthe script, and the starttime
value is calculated at the start of the script and the same value is used for
each appointment created.

Any ideas whats happening?
