It's possible to set the email automatically?

Hi all,

We have a booking calendar set to be only accessed through people in our organization. Making some test, we have realized that once I'm logged into MS Bookings, I am able to make an appointment with any email (including other members emails) making possible to block a buddy calendar making several appointments if I want.

We need to avoid this scenary to start using MS Bookings. There are any way to set automatically the email in the appointment without the needed of specificate it?

Best regards

Luis
