Fix Microsoft Bookings Time Slots Not Appearing After Adding Availability
Question details
The user needs to resolve an issue where newly added availability dates do not display any bookable appointment slots on the booking page.

- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Adding new dates and sessions to an existing Microsoft Bookings page.
- Observed behavior
- The appointment time slots fail to appear on the booking page despite adding availability for those specific dates.
Ensure you have administrator or owner access to the Microsoft Bookings calendar and verify the exact dates where the time slots are missing.
Check and Update Staff Member Availability
Staff-specific availability settings can override general service availability, causing slots to disappear.
Even if the option to use business hours to determine availability is not enabled, individual staff schedules can still block out time slots. For instance, if a staff member is marked as unavailable on a specific day, no sessions will appear for them on that day.
Navigate to your Microsoft Bookings dashboard and select 'Staff' from the left-hand menu.
Click on the specific staff member assigned to the service with the missing sessions.
Review their 'Availability' settings and ensure they are not marked as unavailable on the affected days (e.g., Fridays).
Save the changes and refresh your booking page to verify that the time slots now appear correctly.

Create a New Bookings Profile
A corrupted Bookings profile can cause erratic synchronization behavior that cannot be fixed through settings adjustments.
Contact Microsoft 365 Support
If the issue persists across new profiles, there may be a backend synchronization problem requiring Microsoft's intervention.

Frequently Asked Questions
Why are my Microsoft Bookings time slots missing on specific days?
This usually happens if the assigned staff member is marked as unavailable for those specific days. Individual staff availability settings can override the general service availability rules.
Does the 'use business hours' setting override staff availability in Bookings?
No, staff-specific schedules often take precedence. Even if the 'use business hours' option is disabled, a staff member's custom unavailability will prevent time slots from appearing.
How do I fix a corrupted Microsoft Bookings profile?
If your Bookings profile is corrupted and time slots are not syncing, the most effective workaround is to create a new Bookings calendar from the main dashboard and re-enter your business details.
