Notes about File uploads
- File upload is only available when “Only people in my organization can respond” or “Specific people in my organization can respond” is the selected setting.
- File upload questions are not available for personal forms when Microsoft Information Barrier is enabled. However, you can still create a file upload question by creating a group form.
- If your SharePoint site is moved to a different domain, existing file upload questions will stop working. You’ll need to recreate these questions in the new domain to make them work again.
How to find attachments
When responders upload files for your form question, you can find those files in your OneDrive for Business folder.
- Sign in to OneDrive for Rutgers.
- Select Files, and then choose the Apps folder.
- Select the Microsoft Forms folder.
- Select the file folder matching the name of your form.
- Select the folder of the question that has uploaded files. You'll see the files responders have uploaded to that question.
