Question details
Users report that Microsoft Bookings does not reflect updated service availability, showing limited days even after expanding availability to a full week.

- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Updating service availability and staff working hours for a full week in Microsoft Bookings.
- Observed behavior
- The schedule continues to show only a few available days instead of the newly configured full week availability, despite staff schedules being empty and conflict-free.
Ensure you have administrative access to your Microsoft Bookings calendar and verify that your internet connection is stable before reviewing staff and service settings.
Verify Booking Service and Staff Settings
Check the core configuration settings to ensure service availability, staff working hours, and time zones align correctly.
Microsoft Bookings relies on a combination of service availability, staff working hours, and time zone settings. If any of these are misaligned, the public booking page will fail to display the correct availability slots.
Navigate to the 'Services' tab in Microsoft Bookings, select the affected service, and under 'Availability options', confirm that the schedule is set to 'Bookable when staff are free' or has the correct custom hours applied.
Go to the 'Staff' tab, select the staff member, and uncheck 'Events on Office calendar affect availability' if you want to bypass personal calendar conflicts. Ensure their individual working hours match the required availability.
Click on 'Booking page' in the left menu, scroll to 'Region and time zone settings', and ensure the time zone matches your staff's actual time zone to prevent hidden blocking conflicts.
Click 'Save and publish' on the Booking page to push any backend configuration changes live.

Frequently Asked Questions
Why are my staff members showing as unavailable in Microsoft Bookings?
Staff members might have Office 365 calendar events blocking their time. If the 'Events on Office calendar affect availability' setting is enabled on their profile, personal calendar appointments will automatically mark them as busy in Bookings.
Does changing the time zone affect Bookings availability?
Yes. If the Bookings page time zone differs from the individual staff member's personal time zone settings, it can create misaligned availability blocks and prevent timeslots from appearing correctly.
How long does it take for Bookings availability changes to sync?
Typically, configuration changes update immediately upon saving. However, due to browser caching or temporary Microsoft 365 service delays, it can sometimes take 10 to 15 minutes for the live booking page to reflect the new schedule.
Can I set different availability rules for different services in Bookings?
Yes. You can override the general business hours by selecting a specific service, unchecking 'Use default scheduling policy', and setting custom availability hours exclusively for that service.
