A web-based tool in Microsoft 365 that enables users to quickly create surveys, quizzes, polls, and feedback forms.
Dear Rafael,
There is no such a setting in Microsoft Forms. You may use Power Automate to send the custom emails to users when they fill in their answers.
Here is a demo flow for your reference.
The response has been submitted by @{outputs('Compose')} at @{formatDateTime(outputs('Get_response_details')?['body/submitDate'],'MM/dd/yyyy hh:mm:ss tt')}
Thanks for your effort and time.
Sincerely
