How to anonymise user file uploads in MS Forms

As said, you can't collect files from anonymously with Microsoft forms.

There are three workarounds I know:

- Power Pages is a good option if you're already familiar with it.

- A request files link from OneDrive/SharePoint, included in the form. The con: the uploaded files won't be matched to the form responses.

- A request files link + a Flow. When uploading, users are prompted to enter their first and last name, so if you also ask for their name on the form, you can match files to responses. Even then, you can't fully rule out cases where someone uploads attachments without submitting the form, or vice versa.

If you need something more straightforward, take a look at third-party tools integrated with SharePoint, for instance, Plumsail Forms.
