Currently our users do not receive an email confirmation when they book/reserve a "Space". Only when they reserve a "Desk" do they receive an email.

Can the system be modified to allow the emails for the "Spaces" bookings/reservations also?

Whether the system is modified to provide emails regardless of type of space, or if there is an additional configuration setting to allow/disallow for emails for spaces, is not critical in my opinion. Though it would probably allow for more flexibility to allow the secondary configuration setting for the "Spaces."
