After analyzing the reasons behind receiving duplicate emails in Outlook 2016, it's time to know the various methods to fix this problem.
So, let's have a look.

The first method to get rid of receiving emails is to disable leaving a copy of message on the server. Here are the steps on how to do it:
Step 1: Launch Outlook on your PC.
Step 2: Choose the File tab.
Step 3: Then, hit on the info option>> Account settings.
Step 4: After that, navigate to the E-mail tab.

Step 6: Now, choose the Advanced tab.
And then uncheck 'leave a copy of messages on server.'
Method 2: Disable Antivirus Email Scanning Option
Many antivirus programs scan your emails, which contributes to the problem. When there are so many messages, the software may cause a timeout to the server before returning a signal indicating that the message has been read. As a result, you receive duplicate emails in outlook 2016.
So, you need to disable the antivirus email scanning option from your antivirus program. Follow the below-mentioned steps:
Step 1: Go to your antivirus software.

This option's position will differ based on the software you're running.

If they are not, reactivate your antivirus software.
If you still are receiving duplicate emails in Outlook 365, then try the next method.
Method 3: Turn Off the Rules
If you have rules set up to move the contents of your Inbox's emails to a temporary folder, disable them. Moreover, if you are using Outlook 2007 or later, you do not need to move your email out of the Inbox; change the destination from Account Settings. This will fix the problem of Outlook receiving duplicate emails
