Users are experiencing issues where Microsoft Bookings fails to apply configured date ranges and minimum lead times for appointments.

- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Clients are successfully booking appointments outside the intended date ranges or ignoring the minimum lead-time parameters set by the administrator.
- Observed behavior
- Bookings enforces service hours and meeting duration, but clients can still select any date outside the configured date range and lead-time settings.
Ensure you have administrator or scheduling privileges for the Microsoft Bookings calendar you are trying to configure.
Enable the Default Scheduling Policy for the Service
Applying the default scheduling policy ensures that Bookings respects the calendar's overarching rules for date ranges and lead times.
Log in to your Microsoft 365 account and launch the Microsoft Bookings application.
From the left-hand menu, click on 'Services' to view all your available appointment types.
Select the specific service that is ignoring the date range and lead-time settings to open its configuration page.
Locate the scheduling options section and turn on the toggle for the default scheduling policy so that it follows the main calendar settings.
Save your changes. Open the client-facing booking page to verify that the time slots and date restrictions are now applied correctly.

Try WPS Office for your Document and Productivity Needs
While Microsoft Bookings manages your appointments, you need a reliable office suite to handle contracts, reports, and spreadsheets. WPS Office is a lightweight, fully compatible, and free alternative to Microsoft Office that meets all your daily productivity demands.

Frequently Asked Questions
What is a booking lead time in Microsoft Bookings?
Lead time is the minimum amount of advance notice required before a client can book or cancel an appointment. It prevents last-minute bookings that disrupt your schedule.
Why can clients book dates outside my specified date range?
This usually happens when a specific service has custom scheduling options configured that override or ignore the main calendar's default scheduling policy. Re-enabling the default policy usually resolves this.
Can I set different lead times for different services?
Yes, you can uncheck the default scheduling policy for a specific service in the Services tab, which allows you to set a custom minimum lead time and date range specifically for that offering.
How do I test my booking page before sharing it with clients?
You can click on 'Open published page' from the Microsoft Bookings dashboard to view and interact with your booking page exactly as your clients will see it.
