To get more information on your issue, we want to confirm something with you:
What is the type of your mail account? Is it an exchange account?
Are these duplicate mails in the same folder as original emails? If they are in the same folder, could you try use clean up feature in outlook to remove these duplicate emails? (Select Home > Cleanup) For more details: Remove redundant messages
