Reminders always show 18 hours but the default is set to 10 min

[Guest]

Almost all my users share calendars. When someone post an event on the
calendar the reminder always show 18 hours even though the default is set to
5min. It don’t matter if there making a meeting request or posting that they
have a doctors orpiment.

My question is where else is information stored about reminders (example: a
reg key, some where on the exchange server, an outlook data file)

Please help
Thanks

Almost all my users share calendars. When someone post an event on the

My question is where else is information stored about reminders

data file)

How do they try to create the event? Do they double-click the date? Do
they select New>Appointment? What steps are needed to see this? I ask
because the default all-day event reminder is 18 hours and that's not
configurable. Double-clicking a date to create the event produces an
all-day event to start (which can be changed, of course). Have they tried
highlighting the time span for the event then clicking New? That should
create an even whose start and end times correspond to the start and end
times of the selection and whose default reminder is appropriate to that
type of event.
