Following this guide, users can allow public (non-university) users to upload data along with completing a Microsoft Form. Normally this functionality is not allowed in Forms with “Anyone” visibility; file uploads are restricted to members of the university.

When a Form is set to “Anyone” visibility, you cannot use the File Upload field on the Form. This is a security precaution. Consequently, users must sign into Microsoft 365 with a UConn account in order to upload files into your Form. If “Anyone” was able to upload files into your Form, this would present a clear vector for attack and is therefore not within the built-in functionality of Forms.

This guide will help you circumvent this security precaution and therefore must be followed at your own risk. After completing this guide, any actor or computer on the planet will be able to place files into your OneDrive/SharePoint folder. There will be security precautions listed below. Please read and follow this guide carefully.

Set up

Before receiving files in your account, you must create a folder to hold them.

  1. Visit s.uconn.edu/onedrive or s.uconn.edu/sharepoint and find the location you would like to hold these user-submitted files.

  2. Create a new folder and give it an appropriate name. Example, “questionnaire public file upload”.
    Be sure to create this folder outside of your OneDrive “Documents” folder in order to follow the optional section below.

  3. Back out of the folder so that you can right-click on the folder.

  4. Click on Request Files.

  5. Complete the Request FIles prompt and copy the “Share link”.

  6. Optional: Learn more about the Request Files function: or .

Optional: Precaution - Disable Sync of this folder

For extra security, you may prevent your computer from synchronizing with this folder. Doing so will prevent you from opening the files locally on your computer, instead you will view them through the web browser.

  1. On your computer desktop, click on the OneDrive icon in your menu bar so that the OneDrive window pops up. Click on Settings.

  4. Click Ok to save your changes.

  5. Optional: Learn more about Local Folder Sync here:

Visit either s.uconn.edu/onedrive or s.uconn.edu/sharepoint when it’s time to open these files.

Add the Request Files link to Form

Now that you have created repository to hold the uploaded files, you need to post the link to do so on the Form.

  1. If you have an existing Form, open it now by visiting forms.office.com.
    If you have not yet created a Form, please do so now.

  2. There is more than one way to share this link in the Form because Forms does not allow you to enter a simple read-only line of text.

    1. Create a “Choice” questions and supply only one choice, which is the URL of the Request Files.

      The text you enter in this field will become hyperlinked so that users can click on it.

    2. Create a new Section.

      1. Creating a new Section will require users filling out the Form to click Next at the bottom of the Form. They will be presented with a second page that can hold questions.

      2. Name the Section “File Upload” for example, and then paste the link in the Subtitle.

    3. Explore other options if these two don’t appear as you would like.

  3. Ask your uploaders to be specific with the naming of their files to help you associate the file with their Form submission.

  4. Note: Your changes to the Form are saved automatically when you make them.

  5. Share the Form with others when you are finished.

The data uploaded into the folder you have created will not be linked to the Form. Be sure to check the folder frequently in order to associate the data with specific responses on the Form.
