How to prevent single user but multiple response?

I am learning to use Microsoft Forms. I want to design a form and send to people (without Office 365 account).

 

It is okay for me to set "Anyone with the link can respond". But I tested and found that I can re-input another response after submit the forms even using the same device/browser. As I did not request their identity, is it possible for me to trace their latest choices? Or, is it possible to delete their previous choices?

 

Thanks a lot.

    rather restricting multiple responses, You can use microsoft flow to detect trhe duplicate response and can take action on it further.

      I dont think you can use MS Flow without having a reliable piece of data to use as a condition to decide which action to take. If the form survey is suppose to be anonymous. Since MS forms dont track IP, cookies or some other identifier, i dont see how it can be done.

      I could be wrong, but base on what Im currently aware of, is what I think and agree with RobElliott

        JovianR indeed, how is a flow going to detect a duplicate anonymous response?!

    Only people within your organisation can be set for One response per person. You could filter it out based on the Start or completion time When you export the responses to excel.

      I have faced similar problem. Is there anyway that we can prevent single person replying repeatedly? Before filling the survey? Thank you!

        Benyam_Habesha not with a form that anyone with a link can respond to because, as it's anonymous, Forms has no way of knowing who has completed it.
