Frequently Asked Questions

Why does Microsoft Bookings show the wrong time for my customers?

This usually happens if the option 'Always show time slots in business time zone' is checked in your Booking Page settings, which forces the page to ignore the customer's local browser time zone.

How do I change the default time zone in Microsoft Bookings?

Navigate to your Booking Page settings, scroll down to the 'Region and time zone settings' section, and select your correct local time zone from the dropdown menu.

Can Microsoft Bookings automatically detect a customer's time zone?

Yes, if you uncheck the 'Always show time slots in business time zone' setting, the booking page will automatically detect the customer's browser time zone and display available slots accordingly.
