How to Fix Microsoft Bookings Availability Showing on the Wrong Day
Question details
The user needs to fix a scheduling display error in Microsoft Bookings where customized availability appears one day earlier than configured on the calendar.
- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Configuring custom schedules and appointment availability for specific staff members or services.
- Observed behavior
- Customized availability displays on the previous day (e.g., Monday's schedule appears on Sunday) despite accurate Outlook synchronization, causing appointments to be incorrectly flagged as unavailable.
Verify that your computer's system time zone precisely matches the regional settings intended for your business and staff to rule out local device display issues.
Verify Business, Staff, and Regional Time Zones
A mismatch between the overarching business time zone and an individual staff member's time zone is the most common cause for dates shifting by a full day.
Microsoft Bookings relies on three separate time zone configurations: the Booking Page, the Staff profile, and your device's regional settings. If these are not perfectly aligned, availability can easily shift across the midnight boundary into the previous or next day.
Navigate to the 'Booking Page' tab in your Microsoft Bookings dashboard. Scroll down to 'Region and time zone settings' and confirm it is set to the correct local time zone.
Go to the 'Staff' tab, select the affected employee, and click 'Edit'. Ensure their specific working hours and time zone align perfectly with the overall business setting.
Open the affected staff member's Outlook calendar on the web, navigate to Settings (gear icon) > Calendar > View, and ensure the correct time zone is applied there as well.
Reconfigure Availability from the Services Tab
Bypassing the global business hours and setting custom availability specifically within the Services and Staff tabs can override scheduling glitches.
Report Bookings Defect to Microsoft Support
If all time zone settings are correct and the calendar still displays availability incorrectly, the issue is likely a backend platform defect requiring developer intervention.
Boost Your Business Productivity with WPS Office
While Microsoft Bookings and related scheduling bugs require Microsoft Support, you can handle all your everyday business documentation, spreadsheets, and presentations efficiently and for free with WPS Office. It's a lightweight, highly compatible alternative to the broader Microsoft 365 suite.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button for your operating system.
- 2. Install the Application: Run the downloaded installer file and follow the quick on-screen setup instructions.
- 3. Open Your Documents: Launch WPS Office and instantly open any existing Microsoft Office files with full layout preservation.
Frequently Asked Questions
Why is my Microsoft Bookings showing availability on the previous day?
This usually happens due to a time zone mismatch. If the staff member's time zone, the booking page time zone, or the customer's viewing time zone differ, Microsoft Bookings adjusts the hours, which can push availability back or forward by a calendar day.
How do I stop Microsoft Bookings from using default business hours?
To set unique hours, go to your Bookings portal, select the 'Services' tab, pick a service, and navigate to the assigned staff. Click 'Edit' next to their name and uncheck the 'Use Business Hours' box to define custom availability.
Does syncing Outlook with Microsoft Bookings cause day shifts?
It can if the Outlook calendar is set to a different time zone or region than the Bookings page. Always ensure that the Outlook Web App calendar settings match the Bookings Regional settings perfectly.
What should I do if the calendar shows available, but customers can't book?
This points to a discrepancy between the visual calendar UI and the backend scheduling logic. Verify all settings first. If the problem persists, gather screenshots and submit a service request through the Microsoft 365 Admin Center, as it may be a software defect.
