This week's tip is actually a reminder about making all day reservations in Outlook.
When setting the day and time for a reservation, if you check the "All day event" box, you must change the "Show As:" setting to "Busy." Then no one can make a reservation on top of the one you made.
This is a feature in Outlook that all-day event reservations automatically show as free.
