How to Find or Disable Microsoft Bookings Validation Settings

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Attempting to adjust custom field validations or booking rules for a service but unable to find the required settings in the dashboard.
Observed behavior: The validation settings are not visible in the expected location on the Bookings page, which may be due to account permission levels, organizational configuration, or interface updates.

Before you start

Ensure you are logged into Microsoft 365 with an account that has Administrator access to the specific Bookings calendar, as standard Team Members or Viewers cannot modify validation rules.

Solution 1Recommended

Verify Admin Permissions and Check the Current Bookings Interface

Because validation settings require specific privileges and can move between interface updates, checking your role and exploring the service configuration page is the best first step.

Microsoft frequently updates the Bookings interface, meaning features like validation settings may shift between the 'Classic' and 'New' versions of the app.

Additionally, these settings are restricted to calendar administrators.

Confirm your Administrator role

Log in to Microsoft Bookings. Go to the 'Staff' page in the left navigation menu. Find your name in the staff list and ensure your role is listed as 'Administrator'.

Navigate to Service settings

Click on 'Services' in the left menu, then select the specific service you want to edit. Scroll down to the 'Custom fields' or 'Booking options' section to look for validation toggles.

Toggle the Bookings interface

If you are using the 'New Bookings' interface and cannot find the setting, look for a toggle switch in the top right corner that says 'Try the new Bookings' and turn it off to switch back to the classic view, where the setting might still reside.

Verify Admin Permissions and Check the Current Bookings Interface

Interface Discrepancies: If the setting is completely missing regardless of the interface version, your organization's Microsoft 365 global administrator may have restricted certain customization features.

Solution 2

Consult Microsoft Support or the Tech Community

If validation settings remain unavailable after verifying your permissions, the feature may be temporarily disabled or unavailable for your specific Microsoft 365 tenant version.

Frequently Asked Questions

Why can't I see the validation settings in Microsoft Bookings?

You may lack Administrator permissions for that specific Bookings calendar, or the feature might have been moved during a recent interface update. It is also possible that your organization's IT department has restricted certain customizations.

Who has permission to change rules and settings in Microsoft Bookings?

Only users assigned the 'Administrator' role within a specific Bookings calendar can change scheduling policies, modify service details, and update validation settings. 'Team members' and 'Viewers' cannot make these changes.

Is it better to use the Classic or New Bookings interface to find missing settings?

Because Microsoft is continuously updating the Bookings app, some legacy features or validation rules might only be visible in the Classic interface. Toggling between the two views is a common troubleshooting step for locating missing options.
