A web-based tool in Microsoft 365 that enables users to quickly create surveys, quizzes, polls, and feedback forms.
Hi Brenda,
I'd like to point that it is not feasible to close the form automatically based on the response number. And we can get the response notification mail instead of note mail about the max capacity for the event has been reached.
As a workaround, I 'd like to suggest you let some of your employees notice the number of response in form or the number of notification mail then uncheck Accept responses to close the form. For your reference: Adjust your form or quiz settings in Microsoft Forms.
If you have any concern about that, I'd like to suggest you post a new UserVoice to providing your feedback. This is the best way to improve our products. I appreciate your understanding.
Regards,
Neo
