How to Fix Microsoft Bookings Not Validating Missing Required Fields

Product: Microsoft Bookings
Device & OS: not provided
Scenario: A customer attempts to schedule an appointment but leaves a mandatory field, such as their email address, blank.
Observed behavior: The booking page refreshes immediately without showing any validation error message, and no appointment is created in the system.

Before you start

Solution 1Recommended

Report the Issue to Microsoft Support and the Tech Community

Since this is a known system behavior or bug on the server side, escalating the issue to the specialized Microsoft Bookings support team is the most effective approach.

When Microsoft Bookings fails to trigger validation warnings for missing customer information, the issue usually stems from backend script errors or recent service updates. Engaging directly with Microsoft Support ensures the product team can investigate your specific tenant.

Gather your configuration details

Take screenshots of your current booking page configuration, specifically highlighting the required-field settings. Note down your browser version and language settings.

Post in the Microsoft Tech Community

Navigate to the Microsoft Bookings Tech Community forum (techcommunity.microsoft.com). Create a new post detailing the missing validation error, attaching your screenshots and configuration notes.

Open a Microsoft 365 support request

If you are a Microsoft 365 administrator, log into the Microsoft 365 Admin Center. Go to 'Support' > 'Help & support', describe the validation failure affecting your customers, and open a formal service ticket.

Report the Issue to Microsoft Support and the Tech Community

Provide complete details: Always include whether the issue happens across multiple browsers (like Chrome, Edge, or Safari) to help support agents isolate the problem faster.

Frequently Asked Questions

Why does my Microsoft Bookings page refresh instead of showing an error?

This typically occurs due to a bug in the page's JavaScript validation script, a browser cache conflict, or an ongoing service degradation on Microsoft's end preventing the error prompt from rendering.

How do I make the customer email field mandatory in Microsoft Bookings?

Open your Bookings dashboard, navigate to 'Services', select the service you want to edit, click on 'Custom fields', and check the 'Required' box next to the Customer Email option.

Can I customize the validation error messages in Microsoft Bookings?

No, Microsoft Bookings currently uses standard, built-in validation prompts for required fields. Users cannot customize the specific text of these error messages.
