Question details

A QR code for a Microsoft Forms quiz works for the majority of students but shows a form-not-found error for a few specific users or devices.

Product: Microsoft Forms
Device & OS: not provided
Scenario: Students are attempting to access a Microsoft Forms quiz by scanning a shared QR code in a classroom or remote learning environment.
Observed behavior: The QR code successfully directs most students to the quiz, but selected students receive an error stating the form cannot be found.

Before you start

Ensure that the affected students have a stable internet connection and that their device's camera or QR scanner app is functioning correctly. Have the direct URL link to the form ready as a backup in case the QR code continues to fail.

Solution 1Recommended

Copy URL and Open in an Incognito Window

Bypasses browser cache or account login conflicts that might be causing the form-not-found error on specific devices.

Sometimes, the default browser on a student's device holds cached data or conflicting Microsoft account sessions that prevent the form from loading properly. Using an Incognito or Private window ensures a clean session.

Scan the QR code

Ask the affected student to scan the QR code with their device's camera or QR scanner app as usual.

Copy the URL

Instead of tapping the link to open it directly in the default browser, prompt the student to select the 'Copy URL' or 'Copy Link' option from the scanner screen.

Open Incognito mode

Launch Google Chrome (or the student's preferred web browser) and open a new Incognito or Private browsing window.

Paste and test

Paste the copied URL into the address bar of the Incognito window and press Enter to see if the form loads successfully.

Login Requirement: If the form requires students to be logged in to their school accounts, they will be prompted to sign in manually in the Incognito window. Ensure they have their credentials ready.

Solution 2

Troubleshoot Link and Device Accessibility

Helps isolate whether the problem is specific to a device, the student's account, or the form settings.

Frequently Asked Questions

Why does a Microsoft Form say 'form not found' when scanning a QR code?

This error usually occurs due to browser cache issues, conflicting Microsoft account logins on the device, or restrictive in-app browsers built into certain QR code scanning applications that fail to parse the URL correctly.

Can I share a Microsoft Form without using a QR code?

Yes, you can share the form by copying the direct link from the 'Send' menu, sending it via email, embedding it on a webpage, or sharing it directly through Microsoft Teams.

Does the web browser choice affect opening Microsoft Forms?

Yes, certain mobile browsers or in-app browsers might block essential cookies or fail to pass authentication tokens, leading to loading errors. Using a standard browser like Google Chrome, Safari, or Microsoft Edge is highly recommended.

How do I ensure my Microsoft Form is accessible to all students?

Check the form's 'Share' settings before distributing the QR code. Ensure it is set to 'Anyone can respond' if you do not require students to log in, or 'Only people in my organization can respond' if they are required to use their school accounts.
