Question details
Users need a way to prevent Microsoft Bookings from allowing appointments during times blocked out on subscribed or external calendars.
- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Managing availability and preventing double-booking when using Microsoft Bookings alongside external or subscribed calendars.
- Observed behavior
- Microsoft Bookings blocks time based on the default Outlook calendar but ignores free/busy information from subscribed calendars, allowing clients to book during unavailable times.
Verify that you have full access to your default Microsoft 365 Outlook calendar and confirm exactly which subscribed calendars are currently failing to sync with Bookings.
Manually Copy Events to the Default Outlook Calendar
Since Microsoft Bookings only reads the default Microsoft 365 calendar, copying important blocked times to your primary calendar will prevent double-booking.
Microsoft Bookings is designed to strictly check the primary, default calendar of the assigned staff member. It natively ignores subscribed, shared, or secondary calendars for availability purposes. The most straightforward workaround is to duplicate critical unavailability events onto the main calendar.
Log into your Microsoft 365 account and open the Outlook Calendar web app or desktop application.
Find the event on your subscribed calendar that you want to block out in Microsoft Bookings.
Manually create a new event at the exact same time on your primary default calendar and set its status to 'Busy'.
Open your Microsoft Bookings page and confirm that the specific time slot is no longer available for clients to book.

Frequently Asked Questions
Why does Microsoft Bookings ignore my subscribed calendars?
By design, Microsoft Bookings is configured to pull free/busy data exclusively from the default Microsoft 365 calendar associated with a staff member's account. It does not integrate with subscribed, secondary, or shared calendars for availability checking.
Can I change the default calendar that Microsoft Bookings checks?
No, Microsoft Bookings is hardcoded to check the primary calendar of the Microsoft 365 account linked to the staff profile. You cannot redirect it to check a secondary or subscribed calendar instead.
Will Microsoft add native support for subscribed calendars in Bookings?
While many users have requested this functionality, Microsoft has not provided an official timeline for supporting subscribed calendars in Bookings. It is recommended to check the Microsoft Feedback portal for updates or to upvote the feature request.
