Dear @Holesko, Patrick,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, Microsoft Forms is no longer sending email notifications when responses are submitted, even though submissions are being received. This issue occurred with a form copied from a previous year and persists even after creating a brand-new form. Email notifications are enabled, but no emails are received when teachers submit requests.
For better understanding your situation, could you please confirm some information as:
Is this form owned by you personally or by a Team / Group?
Which type of account are you using (personal account or education account)?
In case you're using Group Form. You can refer to this article No email notifications for responses to Group Forms.
If it does not meet your expectation, please leave the comment below so I can support you more effectively.
Looking forward to your update.
