How to Fix Incorrect Availability and Business Hours in Microsoft Bookings

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Managing staff availability and scheduling client appointments on the Bookings page.
Observed behavior: Available booking dates are hidden, or the system allows clients to schedule appointments outside of the defined business hours due to time zone or calendar conflicts.

Before you start

Ensure you have administrator access to the Microsoft Bookings page and verify the current local time zone for both your business location and your staff's Outlook calendars.

Solution 1Recommended

Adjust Booking Page Time Zone Settings

Disabling the enforcement of the business time zone and ensuring alignment with staff calendars usually resolves availability bugs caused by daylight saving time transitions.

Time zone mismatches between the Bookings page and individual staff calendars are the most common cause of scheduling errors.

This is particularly prevalent immediately following daylight saving time (DST) changes.

Navigate to the Booking Page

Open Microsoft Bookings and select 'Booking Page' from the left-hand navigation menu.

Access Region Settings

Scroll down the page to locate the 'Region and time zone settings' section.

Disable Time Zone Enforcement

Clear the checkbox labeled 'Always show time slots in business time zone'.

Match Staff Calendar

Verify that the Bookings time zone correctly matches the time zone set in the assigned staff member's Outlook calendar.

Save Changes

Click 'Save' at the top of the page to apply the new settings, then refresh your booking page to test the availability view.

Daylight Saving Time Maintenance: It is highly recommended to review these time zone settings after any regional daylight saving time changes to prevent future scheduling errors.

Solution 2

Contact Microsoft 365 Support

If adjusting the time zone settings does not resolve the availability issue, you may need backend troubleshooting from Microsoft Support.

Frequently Asked Questions

Why does Microsoft Bookings allow appointments outside my business hours?

This usually occurs when there is a mismatch between the Booking page time zone and the assigned staff member's Outlook calendar time zone. Clearing the 'Always show time slots in business time zone' setting often resolves this.

How does daylight saving time affect Microsoft Bookings availability?

Daylight saving time transitions can temporarily misalign the default business time zone with actual staff availability on their synced calendars, causing available dates to hide or appear at incorrect times.

Can I set different time zones for different staff members in Bookings?

Microsoft Bookings relies on the individual staff member's Outlook calendar time zone for their specific availability. However, the main Booking page has its own default region setting for customers. Ensuring these align properly prevents scheduling conflicts.

What should I do if my booking page dates are completely hidden?

First, check your 'Region and time zone settings' on the Booking page. If the time zone is incorrect or the business hours are improperly configured for the selected region, the system might block out all availability as a safeguard.
