How to Prevent a Customer from Making New Appointments in Microsoft Bookings

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Managing customer access and preventing unwanted or duplicate appointments from specific clients.
Observed behavior: Microsoft Bookings lacks a direct option in the Customers tab to block an individual or restrict them to a single booking, allowing them to freely create additional appointments.

Before you start

Since Microsoft Bookings does not currently feature a native 'block list' or a strict one-customer booking limit, managing unwanted appointments requires adjusting your overall service settings and utilizing manual approval workflows.

Solution 1Recommended

Implement Manual Booking Approvals and Restrictions

Modify your booking page settings to require manual intervention, giving you the power to vet and reject unwanted appointments before they are confirmed.

While you cannot block a specific email address from accessing the public booking link, you can change how appointments are processed. By disabling automatic confirmations or hiding the page from search engines, you gain more control over your schedule.

Hide your booking page from search engines

Navigate to the 'Booking page' settings in Microsoft Bookings. Check the box for 'Disable direct search engine indexing of booking page' so only people with the direct link can find it.

Manually manage and cancel unwanted bookings

Since you cannot block the customer upfront, monitor your Bookings calendar. If a disqualified customer makes an appointment, click on the appointment in the calendar and select 'Cancel', then optionally send them a cancellation message.

Adjust minimum lead times

Go to 'Services' and edit the specific service. Under 'Scheduling policy', increase the 'Minimum lead time' to prevent customers from booking last-minute duplicate appointments, giving you time to review incoming requests.

Implement Manual Booking Approvals and Restrictions

Alternative Approach: If you are using Microsoft Teams alongside Bookings, consider utilizing the Virtual Appointments app features for additional control over attendee lobbies and meeting entry.

Solution 2

Request Tenant-Level Controls via Microsoft Admin

Work with your IT administrator or Microsoft Support to explore advanced restrictions and submit feature feedback for future updates.

Frequently Asked Questions

Can I block a specific email address from Microsoft Bookings?

Currently, Microsoft Bookings does not have a native block list feature for specific email addresses. You must manually cancel unwanted appointments or set up Exchange mail flow rules via your IT administrator.

How do I stop customers from creating duplicate bookings instead of rescheduling?

Bookings does not currently restrict a single user from making multiple appointments. To minimize this, you can adjust your service scheduling policy to require longer lead times or manually instruct clients to use the 'Reschedule' link found in their original confirmation email.

Is there a way to require approval before a booking is confirmed?

Microsoft Bookings generally confirms appointments automatically. However, you can manage availability tightly or use third-party integrations via Power Automate to create custom approval workflows before an appointment is officially added to your calendar.
