Sync All Day Events
Enable this (make sure the switch is green) if you want Appointment Reminder to sync all day events. One thing to consider when syncing All Day Events is when will the reminder messages be delivered. If your reminders are set to send 24 hours before the appointment time (All day events start at midnight) then these all day events would receive the reminders at midnight the night before (you probably don't what this!). To prevent this from happening either change your "when to send" time to custom (and maybe set all your reminders to go at the day before at 1 p.m for example), or alternatively or can adjust your business settings to only send reminders during business hours. If you choose this option make sure set the start and end hours for this calendar.
