- Scenario

Consult the Microsoft Bookings Community Hub
Since Microsoft Bookings lacks a built-in feature to prevent multiple customer appointments, contacting technical specialists is the best approach to find custom account configurations.
Currently, Microsoft Bookings does not provide a straightforward setting to restrict a single customer from making multiple appointments. Engaging with Microsoft technical specialists can help you explore advanced workarounds or beta features.
Open your web browser and navigate to the official Microsoft Tech Community website, then locate the Microsoft Bookings Community Hub.
Click the 'Sign In' button at the top right corner and log in using your Microsoft 365 administrator credentials.
Click on 'Start a New Discussion' and explain your specific scenario, mentioning that you require a 72-hour notice and need to restrict customers from holding multiple overlapping appointments.

Enforce a 72-Hour Lead Time Policy
While this doesn't directly stop multiple bookings, updating your scheduling policy enforces the 72-hour notice requirement for all bookings and cancellations.
Manage Your Business Documents Efficiently with WPS Office
While you rely on Microsoft Bookings for scheduling, handling your daily business documents shouldn't be complicated or expensive. WPS Office is a free, lightweight, and powerful alternative to Microsoft Office that meets all your document processing needs with seamless format compatibility.
- 1. Download the Installer: Visit the official WPS Office website and click the 'Free Download' button to get the setup file.
- 2. Install WPS Office: Run the downloaded installer and follow the on-screen instructions to install the suite on your device.
- 3. Open and Edit Your Files: Launch WPS Office and open your existing Microsoft Office files. They will display perfectly without any formatting issues.

Frequently Asked Questions
Can I limit the maximum number of appointments a customer can book in Microsoft Bookings?
Currently, Microsoft Bookings does not offer a native setting to restrict the number of appointments a single customer can book. You can only control maximum attendees per specific service, not per individual customer across the calendar.
How do I enforce a strict cancellation policy in Microsoft Bookings?
You can enforce a cancellation policy by going to your Booking Page settings, locating the Scheduling Policy section, and setting the 'Minimum lead time' for cancellations and bookings (e.g., to 72 hours). Customers will not be able to cancel or book within that timeframe.
Will Microsoft add a feature to prevent duplicate bookings?
Microsoft continuously updates its 365 suite based on user feedback. It is highly recommended to vote on or submit this feature request in the Microsoft Feedback Portal or the Bookings Community Hub so the development team can prioritize it.
