Microsoft Bookings – Booking updates are not reflected in staff members' Teams calendars

For about a week, we have been experiencing an issue with Microsoft Bookings.

The problem is that changes made to bookings are not being reflected in the assigned staff members' calendars in Microsoft Teams (Outlook calendar), even though everything appears correct from the administrator's side in Microsoft Bookings.

For example:

One staff member was scheduled to meet with five customers. One of those customers cancelled their appointment, so I removed them from the booking and replaced them with another customer. However, the staff member's Teams calendar still showed the cancelled customer instead of the new one.

Two appointments were cancelled and replaced with new bookings. In Microsoft Bookings, the new customers were correctly assigned to those time slots, and the Teams meeting links were generated successfully. However, in the staff member's Teams calendar, those time slots appeared as empty, as if no appointments had been booked.

From the administrator's perspective, all bookings are correct and up to date in Microsoft Bookings. The issue only affects the assigned staff members, whose Teams calendars do not display the latest booking updates and instead show outdated or missing appointments.

Could you please investigate why the changes made in Microsoft Bookings are not synchronizing correctly with the staff members' Teams/Outlook calendars?

Thank you for your assistance.
