Collect files from customers outside your Microsoft organization

A public text-only Microsoft Form and a form with a file-upload question have different access rules. Microsoft documents that file uploads require an organization-restricted response setting. Selecting a public audience does not make that upload field available to everyone.

For an external client, try a Youform intake with a name, project description, and upload question. Free allows files up to 10MB each. Open the public form while signed out of the creator account and check the file requirement, upload allowance, and destination for the new response.

Start from a file-upload form template. Keep employee-only forms in a workflow that meets your organization’s access requirements; collecting a customer file is a different job.
