Since the migration from Outlook 2003 and Exchange 2003 to Outlook 2007 and Exchange 2010 we have a problem with the reminders of all day events. Since the default reminder is 18 hours before the appointment, we learned our users to set the reminder to none, but now users recieve a reminder at 23:45 before the appointment starts.
This is the default reminder of Outlook 2007 for appointments, which overrules the reminder "none" of the all day event.
Does someone has a solution to solve this permanent, instead of a workaround, mentioned below.
Setting the default reminder of Outlook 2007 to 0 minutes could be a workaround. But then you must set a reminder for your own apppointments. Or we could learn our users to set a reminder of 12 hours.
A similar problem was know with Exchange 2007, see http://support.microsoft.com/default.aspx?scid=kb;en-us;973761
