Question details

The user wants to allow respondents to upload files as part of their Microsoft Forms submission.

How to Add File Upload Questions in Microsoft Forms

Product: Microsoft Forms
Device & OS: not provided
Scenario: Creating a survey, quiz, or data collection form that requires users to submit external documents or images.
Observed behavior: Setting up the file upload question type, confirming the creation of the storage folder, and configuring file restrictions like count, size, and type.

Before you start

Ensure you are using a Microsoft 365 business, education, or enterprise account, and verify that your form settings restrict responses to people within your organization, as anonymous and external file uploads are not supported.

Solution 1Recommended

Add and Configure a File Upload Question

Use the extended question types menu to insert a file upload prompt and define the allowed file properties.

File upload functionality requires respondents to be authenticated within your Microsoft 365 organization. The uploaded files will be securely saved to a newly generated folder in your OneDrive for Business or SharePoint.

Access the Form

Select File Upload Question Type

Click the 'Add new' button, click the dropdown arrow for 'More question types' on the right side of the options, and select 'File upload'.

Confirm Storage Creation

A prompt will appear stating that a new folder will be created in your OneDrive for Business. Click 'Yes' or 'OK' to proceed.

Configure Limits

Enter your question text. Below it, use the dropdown menus to select the 'File number limit' (up to 10 files) and the 'Single file size limit' (choose between 10 MB, 100 MB, or 1 GB).

Restrict File Types

To specify exact file formats, click the three-dot menu (More settings for question) at the bottom right of the question box, select 'File type', and check the boxes for permitted formats like Word, Excel, PPT, PDF, Image, Video, or Audio.

Add and Configure a File Upload Question

External sharing limitation: If you later change your form's share settings to 'Anyone can respond', the file upload question will be automatically disabled and hidden from respondents.

Frequently Asked Questions

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

The file upload feature is only available for Microsoft 365 business, education, and enterprise accounts. It will be greyed out if you are using a personal Microsoft account or if your form is set to allow 'Anyone can respond' instead of restricting it to internal users.

Where are the uploaded files saved when respondents submit the form?

For personal forms, uploaded files are stored in a dedicated folder in your OneDrive for Business under Apps > Microsoft Forms. For group forms, the files are stored in the default SharePoint document library associated with that Microsoft 365 group.

Can I increase the maximum file size limit beyond 1 GB?

No, Microsoft Forms currently caps the single file size limit at 1 GB per file. You can choose between 10 MB, 100 MB, and 1 GB in the question configuration settings.
