Dear Jon Goldaracena Murguialday,
Good day! Thank you for posting to Microsoft Community. We are happy to help you
I'm sorry to hear that you're experiencing this issue with Microsoft Forms. Based on the information you provided, it seems that the form has been deleted or removed from your account. However, the link to the form is still active and responses can still be submitted.
Targeting the current phenomenon, we kindly recommended you can contact the admin user to raise a service request in Microsoft 365 admin center, which the support there has the related permission and resource to help you check from the backend and see whether can help to recover the data you did not sync successfully.
Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
