How to Add Reference Documents and File Uploads in Microsoft Forms

Product: Microsoft Forms
Device & OS: not provided
Scenario: Creating a form or survey that requires participants to view a reference document and upload a file in response.
Observed behavior: Microsoft Forms restricts direct file attachments to questions and limits the file upload response feature based on organizational settings and account types.

Before you start

Verify whether your form respondents are inside or outside your organization, as Microsoft Forms natively restricts file uploads to internal members only.

Solution 1Recommended

Use Cloud Links for References and Enable Internal File Uploads

Work around attachment limitations by sharing cloud links to reference files and using the built-in File Upload question for internal respondents.

Since Microsoft Forms does not allow direct document attachments to questions, you must host your reference files externally. Furthermore, the file upload question type is strictly limited to users within the same organization as the form creator.

Upload Reference Document

Upload your reference document (e.g., PDF or Word file) to OneDrive or SharePoint and generate a shared link with appropriate access permissions.

Insert Link into the Form

In Microsoft Forms, select your question, enable the 'Subtitle' option if needed, and paste the shared link so respondents can click and view the reference file.

Add File Upload Question

Click 'Add new' to create a new question, click the dropdown arrow for more question types, and select 'File upload'.

Configure File Limits

Set the parameters for the upload, including the file number limit, maximum single file size, and allowed file types.

Use Cloud Links for References and Enable Internal File Uploads

Important Restriction: Adding a 'File upload' question automatically changes the form's sharing settings to 'Only people in my organization can respond'. Anonymous or external respondents will not be able to fill out the form.

Solution 2

Collect External Files via Cloud Folders

If you are surveying people outside your organization, you cannot use the standard file upload question and must provide a shared folder link instead.

Frequently Asked Questions

Why is the file upload option missing or grayed out in Microsoft Forms?

The file upload option is only available when the form settings restrict responses to internal users. It is unsupported and grayed out if your form is set to 'Anyone can respond' or if you are using certain personal Microsoft accounts.

Can I attach a PDF directly to a Microsoft Forms question?

No, Microsoft Forms does not support directly embedding or attaching files like PDFs to questions. You must upload the file to a cloud service like OneDrive and paste the shareable link into the question text or subtitle.

How do I request better file upload features from Microsoft?

You can suggest new features or report form limitations directly to Microsoft by visiting the Microsoft Feedback portal at feedbackportal.microsoft.com.
