I have Windows Live Mail calendar set to deliver email reminders to me, with the amount of advance notice stipulated, but the advance notice period is not being observed.

For example, I have a fortnightly recurring event, set for 6 AM, which I have set to email me at five minutes notice.

The event does trigger every fortnight, but the email is always sent 24 hours in advance, at 6 AM the day before (give or take a few minutes), instead of at 5:55 AM on the day of the event.

Please advise.
