Bookings MS - Group Appointment - One customer cancels, it is cancelled for everyone (Customer+staff

New Contributor

I already have seen that this problem was notified but it still don't have any answer for 2 years :

I have created group appointment up to 100 people.

When one of the customer cancels it (it seems that it is specifically customer with a gmail email address) - from his email notification or via google calendar - it cancelled the appointment for everyone.

We set up the service to disable the functionnality "Allow clients to manage their appointments when booked by you or your team on their behalf" in base details, but we still have the option to cancel it as customer.


Another intriguing part is that you can find this option "Let customers manage their own appointments" for each appointment created, that you have to manually uncheck it for all of them, but in any case, it does not block the cancellation by a customer. Moreover, when a customer cancels, this option becomes active again automatically.


Is there not a solution that will be applied urgently on this subject?
This is a frustration for the customers and clearly a lack of viability

I also have the same issue. Whenever I have a group booking and someone cancels, everybody gets a cancellation notification and even my staff doesn't see the booking in their calendar. 


As an administrator, I do see the booking in Calendar everything looks OK. 

I detected this issue when lots of customers complained about this confusion. Is there anything we can change in the setup to prevent this from happening?

Hi @jcarballo1993 ,

To date, we have not found a solution in the settings of Bookings. And this bug seems to exist for several years without any answer from Microsoft.
We tried to ask other service providers using the solution who also found the same problem.
This seems to be a development issue on the part of Microsoft directly.
If we don't get an answer in the next few days, we will unfortunately have to find a more viable solution for group meeting booking.
