Question details
The user wants to configure Microsoft Bookings so customers can book appointments up until exactly midnight the day before the scheduled appointment.

- Product

- Device & OS
- not provided
- Scenario
- Setting a strict, day-before calendar time cutoff for customers attempting to schedule appointments online.
- Observed behavior
- Microsoft Bookings currently only allows lead times measured in floating hours, which blocks morning and evening appointments at varying times instead of establishing a fixed midnight cutoff.
Note that Microsoft Bookings calculates lead time backwards from the exact hour of the appointment, not based on fixed calendar days or clock times.
Use an 8 to 10-Hour Lead Time Workaround
Optimize the floating lead time to closely simulate a midnight cutoff for your morning appointments.
Since Microsoft Bookings does not support a fixed clock-time cutoff like midnight, using an 8 to 10-hour lead time is the most effective workaround. This configuration keeps morning appointments (e.g., 8:00 AM) open for booking until midnight the night before.
Log into Microsoft Bookings and select 'Booking page' from the left-hand navigation menu.
Scroll down to the 'Scheduling policy' section where you can adjust time increments and lead times.
Set the 'Minimum lead time for bookings and cancellations' to 8 or 10 hours, then save your changes.

Submit a Feature Request to Microsoft
Because a fixed midnight cutoff is a highly requested missing feature, submitting feedback helps Microsoft prioritize its development.

Frequently Asked Questions
Can I set lead times by days instead of hours in Microsoft Bookings?
No, Microsoft Bookings exclusively calculates lead time in hours. If you set a lead time of 24 hours, it will block appointments exactly 24 hours before the specific appointment time, not based on calendar days.
Does Microsoft Bookings allow different cutoff times for different services?
Yes, you can override the general scheduling policy for individual services. Go to the 'Services' tab, select a specific service, and adjust the minimum lead time under its specific scheduling policy options.
Why are my evening appointments closing early for bookings?
If you use a short lead time (like 8 hours) to keep morning slots open until midnight, the same 8-hour rule applies backwards to evening slots. Thus, a 4:00 PM appointment will close for booking at 8:00 AM on the same day.
