Hi @Baker, Martin,
Good day to you! Welcome to Microsoft Q&A forum.
Thank you for reaching out. I understand you're experiencing an issue where Microsoft Bookings is allowing appointments as early as 6:30 AM, even though you've set your availability to begin at 9:30 AM. I’d be happy to help clarify and guide you through troubleshooting this.
Are you able to check the following workaround using the desktop app or web version of Microsoft Bookings? Because these settings can only be configured through the web interface or desktop app, not via mobile.
Microsoft Bookings pulls availability from several layers of settings, and a mismatch in any of these can cause unexpected time slots to appear:
1. Time zone mismatch
Bookings uses time zone settings from both your Booking page and your Outlook calendar. If these don’t match, it can cause incorrect time slots to appear.
- Go to Microsoft Bookings > Booking Page
- Expand Region and time zone settings
- Ensure the Current time zone matches your Outlook calendar’s time zone
Set Bookings language and time zones
2. Service-Specific availability overrides
Each service in Bookings can have its own availability settings that override your general business hours.
- Go to Services > Edit Service
- Scroll to Availability
- Make sure it’s set to “Bookable when staff are free” or that custom hours match your intended schedule
Configure service availability
3. Staff calendar conflicts
Bookings may allow bookings based on your Outlook calendar’s availability. If your calendar shows early hours as “Free,” Bookings may consider them bookable.
- Go to Staff > Edit Staff Member
- Uncheck “Events on Office calendar affect availability” to test if this resolves the issue
4. “Always Show Time Slots in Business Time Zone” setting
This setting affects how time slots are displayed to customers. If disabled, customers may see and book times based on their own time zone.
- Go to Booking Page Settings
- Try unchecking “Always show time slots in business time zone” and test again
I hope this message finds you well and if there’s anything else I can help with, just let me know. I’m happy to help.
Wishing you a great day.
