Question details

The user needs to correct Microsoft Bookings so that it displays appointment times in British Summer Time (BST) rather than defaulting to UTC.

How to Fix Microsoft Bookings Showing UK Time as UTC Instead of BST

Product: Microsoft Bookings
Device & OS: not provided
Scenario: Scheduling appointments and managing booking pages during the British Summer Time period in the UK.
Observed behavior: Microsoft Bookings incorrectly displays UK appointment times and calendar invitations as UTC, ignoring the current daylight saving time offset (BST).

Before you start

Ensure you have administrator or owner permissions for the Microsoft Bookings calendar, as you will need access to modify the main Booking page settings.

Solution 1Recommended

Verify and Update Booking Page Region Settings

Manually re-selecting the correct UK time zone in the Booking page settings often forces the system to recognize the British Summer Time offset.

Sometimes the time zone settings default to UTC or fail to automatically adjust for daylight saving time. Updating the region configuration explicitly can resolve this synchronization issue.

Access Microsoft Bookings

Log into your Microsoft 365 account and open the Microsoft Bookings application.

Navigate to the Booking Page

From the left-hand navigation menu, click on 'Booking page' to open your public scheduling settings.

Update Region and Time Zone

Scroll down to find the 'Region and time zone settings' section. Click on it to expand the options.

Select the UK Time Zone and Save

Ensure the 'Current time zone' is correctly set to the UK time zone (London). Save the changes and refresh your booking page to check if BST is now applied.

Verify and Update Booking Page Region Settings

Clear Browser Cache: After saving the changes, view your booking page in an incognito window or clear your browser cache to ensure you are seeing the updated time format.

Solution 2

Report Known Issue to Microsoft Support

If the region settings are already correct but the problem persists, you may be experiencing a known software bug that requires support intervention.

Frequently Asked Questions

Why is my Bookings calendar showing UTC instead of my local UK time?

This commonly occurs if the regional settings on your Booking page are misconfigured, or due to a known synchronization bug within Microsoft 365 where daylight saving time (BST) fails to trigger properly.

Can I let customers view appointments in their own local time zone?

Yes. In the Microsoft Bookings page settings, you can uncheck the option labeled 'Always show time slots in business time zone'. This allows the scheduling page to automatically adapt to the customer's local time zone when they view it.

Does updating the time zone fix calendar invitations already sent out?

Generally, no. Adjusting the time zone primarily affects future bookings and the immediate display of your public booking page. Existing calendar invitations sent with the incorrect UTC time may need to be canceled and rebooked.
