The user needs Microsoft Bookings to correctly block off unavailable times based on manually added events in a staff member's new Outlook calendar.

How to Fix Microsoft Bookings Not Blocking Outlook Calendar Events

Product: Microsoft Bookings and Outlook
Device & OS: not provided
Scenario: Customers are successfully booking appointments during times when a staff member already has a manually scheduled event in their Outlook calendar.
Observed behavior: Microsoft Bookings does not recognize the manual events from the new Outlook calendar, leaving those time slots available for booking.

Before you start

Ensure you have administrative access to Microsoft Bookings and that the affected staff member has a valid Microsoft 365 license assigned with active calendar permissions.

Solution 1Recommended

Verify Calendar Settings and Staff Availability Options

Ensure that the staff member's primary Exchange calendar is being used and that Bookings is permitted to read their availability.

Microsoft Bookings relies on the primary Microsoft 365 Exchange calendar to determine free/busy times. If events are added to a secondary calendar, Bookings will ignore them.

Access Staff Settings

Open the Microsoft Bookings dashboard and navigate to the 'Staff' page from the left-hand menu.

Edit Staff Profile

Select the affected staff member's name and click on 'Edit staff'.

Enable Office Calendar Sync

Scroll down to the 'Availability' section and ensure the option 'Events on Office calendar affect availability' is checked.

Confirm Primary Calendar Usage

Verify with the staff member that they are adding their manual events directly to their primary Microsoft 365 Exchange calendar, rather than a shared or secondary calendar.

Verify Calendar Settings and Staff Availability Options

Event Status: Ensure that manually added events in Outlook have their 'Show As' status set to 'Busy'. Events set to 'Free' will not block times in Bookings.

Solution 2

Test Synchronization with Classic Outlook

The new Outlook experience can sometimes experience synchronization delays. Reverting to classic Outlook temporarily can help force the calendar to update with Bookings.

Frequently Asked Questions

Why is Microsoft Bookings not reading my Outlook calendar events?

This typically occurs if manual events are added to a secondary or shared calendar instead of the primary Microsoft 365 Exchange calendar. It can also happen if the 'Events on Office calendar affect availability' setting is unchecked in the Bookings staff profile.

How long does it take for Outlook events to sync with Microsoft Bookings?

Usually, Outlook calendar updates reflect in Microsoft Bookings almost instantly or within a few minutes. If you are using the new Outlook and experiencing extended delays, switching to classic Outlook temporarily can often force a synchronization.

Does Bookings block time for events marked as 'Free'?

No, Microsoft Bookings only blocks availability for events that are marked as 'Busy', 'Tentative', or 'Out of Office' in your Outlook calendar. You must ensure your manually added events are set to 'Busy' to prevent double booking.
