Email Field in Bookings

Hello,

We are an independent school and use Microsoft Bookings for many events. However I would like to know if there is a feature where as the Email field when booking can be restricted to a certain format and containing certain words. For example .stu@domain.edu.mt would be required in the email field.

We have guest access turned off due to our school policies and we send the booking page restricted with login. Parents & Children, even tough instructed countless times to write down the student email when booking, end up still writing their personal one and/or spelling mistakes such as forgetting .stu in the email. This then becomes a real headache since I need to go into customers and check each booking 1 by 1 fixing those invalid emails.

Any way about this?

Regards,
