reduce 2 read receipt for exchange 2013 pop3 users

How to reduce the POP3 read receipt responses which sends two response mails

I am having Exchange 2013 on Windows 2012. The clients are only POP3 users.

When a mail is sent from outlook choosing read receipt. When the mail is read, the users get two responses.

First responses :

We want to reduce the two responses, kindly suggest.

Does the server rule will help to suppress? if yes how?

Is there any registry or powershell command to suppress?

Check to see if the POP users are receiving mail and invites on two computers (I do). That can cause the 2 responses.

 Set-PopSettings  -SuppressReadReceipt  $true

This command reduced the responses to one.
