Verify Quiz Settings and Create a Test Quiz

Since Microsoft Forms typically treats any unmarked option as incorrect by default, verifying your settings and testing a fresh quiz can help identify if your current form is corrupted.

In Microsoft Forms, you designate the 'Correct' answer by clicking the checkmark next to the option. Any option without this checkmark is automatically graded as incorrect. If the interface is behaving unexpectedly, running a quick diagnostic test is recommended.

Review current answer settings

Open your Microsoft Form, click on the quiz question to expand it, and ensure that only the correct answers have the green checkmark selected.

Create a new diagnostic quiz

Return to the Forms homepage, click 'New Quiz', add a multiple-choice question, and test if the correct/incorrect grading logic works as expected in a fresh file.

Check tenant-wide issues

Ask colleagues if they are experiencing similar behavior. If the issue is widespread across your organization, capture screenshots of the missing options and contact Microsoft Support.

Documenting the Issue: If you need to contact support, be sure to record exactly how the quiz was created (e.g., from scratch or duplicated from a template) to assist with troubleshooting.
