Hi Natalie,
Thank you for querying in this forum.
From your description, it seems that you have created the Microsoft Forms for daily announcements, and you want to delete the responses of this form instead of duplicating or recreating the form.
May I know if my understanding is right? If so, if you just want to delete the responses in Microsoft form daily, you can go to Microsoft Forms > click Reponses > click Ellipsis > Delete All responses, as shown below:
Note: if you delete those responses, you may not recover them.
If the scenario above is not consistent with yours, you can also post back and provide more details about it.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Best Regards,
Sukie
