Here are some steps you can take to preview your Microsoft Forms form before sharing it:

1. Create a test form page to view your questions and the design of the page.
2. Set the form submission limit to a low number to practice answering the questions.
3. Preview the welcomes, conclusion, and thank you pages.
4. Save a copy of the preview as a draft form and look for errors.
5. Share the test form with a few people to make sure everything looks correct.
