- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Configuring custom business and service hours for client appointments.
- Observed behavior
- Nighttime availability continues to display even after custom business and service hours are configured.
Ensure you have administrator access to the Microsoft Bookings calendar you are modifying, as staff-level access may not permit changes to global availability or scheduling policies.
Verify Business Hours and Staff Availability Settings
Check both the global business hours and individual staff availability settings, as staff-specific settings can override your global calendar hours.
In Microsoft Bookings, the availability shown to customers is a combination of the global booking page settings, specific service settings, and individual staff schedules. If overnight hours are showing, one of these overlapping settings is likely misconfigured.
Log in to Microsoft 365, open the Bookings app, and navigate to the 'Booking page' tab on the left sidebar. Ensure your 'Business hours' are set correctly and do not include overnight time slots.
Go to the 'Staff' tab and select individual staff members. Make sure 'Use business hours' is checked, or if they have custom hours, verify that their specific schedule does not include overnight availability.
Check the 'Services' tab. Open each service and look at the 'Availability options'. Ensure the service isn't configured with special availability that overrides the general booking page settings.

Seek Specialized Help in the Microsoft Tech Community
If nighttime availability persists after properly configuring all settings, consult the dedicated Microsoft Bookings community for specialized troubleshooting.
Manage Your Documents Effectively with WPS Office

Frequently Asked Questions
Why does my Bookings page show hours outside my set business hours?
This typically occurs because individual staff availability or specific service settings are overriding the global Booking page business hours. Check both the Staff and Services tabs to align them with your standard business hours.
Can I set different working hours for different staff members?
Yes, in Microsoft Bookings, you can uncheck the 'Use business hours' option in a staff member's profile and set custom hours specific to their personal schedule.
Does time zone affect Microsoft Bookings availability?
Yes, if your Bookings page is set to a different time zone than your clients, it may appear as though overnight hours are available. Ensure the 'Always show time slots in business time zone' setting is configured correctly based on your target audience.
