How to Fix Microsoft Forms File Submission Missing or Empty in Teams
Product
Microsoft Forms and Teams
Device & OS
not provided
Scenario
Submitting a required file upload for a school assignment using Microsoft Forms within Microsoft Teams.
Observed behavior
The teacher can see the student's name and submission time, but the uploaded file appears empty or missing. The student is unable to verify the upload because Microsoft Forms does not provide a complete submission history by default.
Before you start

Check your school email account, including the spam or junk folder, for a submission receipt or confirmation email from Microsoft Forms to use as proof of your upload.

Solution 1Recommended

Locate Submission Evidence and Contact the Teacher

Gather any available proof of your submission and ask the teacher to reopen the assignment so you can upload the file again.

Microsoft Forms restricts respondents from viewing their past submissions unless they opted to receive an email receipt before clicking submit. Because the form was restricted to a single submission, only the teacher or administrator can reset your status.

1
Search for an email receipt

Log into your school email and search for 'Microsoft Forms'. Look for an automated email detailing your answers and file upload. Take a screenshot if you find it.

2
Contact your teacher via Teams

Send a direct message to your teacher in Microsoft Teams explaining that a glitch caused your mandatory file to appear empty on their end. Provide your screenshot if available.

3
Request to reopen the assignment

Ask the teacher to either delete your previous attempt in Microsoft Forms to allow a fresh submission or to reopen the Microsoft Teams assignment so you can attach the file directly to the assignment instead of the Form.

Why the file is missing: Occasionally, browser interruptions or sync delays between SharePoint (where Teams stores files) and Microsoft Forms can result in a blank file being registered.

Frequently Asked Questions

Why does my uploaded file appear empty in Microsoft Forms?

This is usually caused by a network interruption during the upload process, a browser cache issue, or a syncing delay between Microsoft Forms and the SharePoint folder where the files are stored.

Can I check my Microsoft Forms submission history?

By default, Microsoft Forms does not provide respondents with a dashboard to view past submissions. You can only view your answers if the form creator enabled the 'Send email receipt to respondents' option and you selected it before submitting.

How can I resubmit a Form in Teams if it says I already responded?

If the form is set to 'One response per person', you cannot resubmit it yourself. You must ask the teacher or the form owner to delete your original response in the Forms 'Responses' tab, which will allow you to submit again.
