When we create a series and invite a resource with MultipleBookings 1 to the series, it gets created and the resource is booked.
When we now delete an event from the series in our personal calender, the exception is not reflected on the resources calender and it is then not possible to invite the resource to another event that takes place on the exceptions date.
We worked around this with multipleBookings 2 but the deleted event still exists
on the resources calender and might be confusing.
