Notification on saved adobe form when unfilled "required fields not completed on save and exit

[manwacmike]

I have a question.  I recently created a form with some fields that were "required". The form seemed to work well.  I noticed some of the users were not populating the required fields but were able to save the form and close the file and did not get some type of notification that they did not fill out the the required fields. Is this how acrobat works? I would have expected some type of notification. Can you explain why this happens? I have adobe acrobat pro 2020.

The required property is not for warnings when saving, or the prevention of saving, it is for warning and prevention of submitting forms when the required fields are not completed.  You would have to create your own script for that.
