How to Retrieve Data ?

Try this:

1. Check OneDrive or SharePoint: If the form was created using Microsoft Forms, the responses might be saved in an Excel file on OneDrive or SharePoint. Look for a file named after the form in the root directory or a specific folder.
2. Version History: If you find the Excel file, you can use the version history feature to restore a previous version of the file that contains the data before the form stopped working.
3. Microsoft Forms Admin Center: If you have admin access, you can check the Microsoft Forms Admin Center to see if the form is listed there. Sometimes, forms can be restored from the admin center.
4. Check the Trash: If the form was accidentally deleted, it might be in the trash folder of the account that created it. Check the trash folder in OneDrive or SharePoint.
5. Microsoft Graph API: If the form owner’s account has been disabled or deleted, you can use the Microsoft Graph API to check if the form data can be retrieve.
