Solutions to Fix ‘Outlook is Sending Multiple Copies of an Email’

To fix Outlook 2016 sending multiple copies of emails, you need to address the right cause first and then we will take steps accordingly. Some of the solutions based on causes are as follows:

#1. MS Outlook and Virus Scanner are Integrated

When the Antivirus program installed on your system gets integrated with MS Outlook, Outlook can create mail duplicates. The virus scanner scans all activities taking place and thus scans all incoming and outgoing mail. Therefore, you need to disable the antivirus for some time. After that, try to send emails from Outlook, if you see no mail duplicates you need to uninstall the Antivirus application. However, if the “Outlook sending two copies of email” problem persists, switch to another method.

#2. Send/Receive Mail Time Interval

If the send/receive task interval is set for a short period, say less than 5 minutes. Then, it takes time for the mail to be uploaded to the mail server. Meanwhile, the next send/receive process starts even before the previous process is completed. As a result, the mail is saved in the Outbox to send it later. Therefore, you need to change the Send/Receive time gap by following the steps given below.

For Outlook 2007 and older versions:

• Go to the ‘Tools” tab
• Click on the Options button.
• Now, click Mail Setup and then, go to Send/Receive.

For Outlook 2010 and 2013

• Go to File and click Options.
• Then, click on Advanced.
• Send/Receive for changing time interval.

Note: By default Send/Receive time interval is 30 minutes. You must set the time interval for more than 5 minutes. And if more than 3 Outlook accounts are configured, it should not be lower than 10 minutes.

#3. Check Server TimeOut

Another reason why Outlook is sending multiple copies of an email can be Server Timeout. As you know, both IMAP and POP3 work according to server timeout. And the minimum required timeout is 1 Minute. Therefore, if an Outlook user is working with a slow connection, it’s needed to increase the server timeout to avoid duplicate emails. Follow the steps as directed below:

• Open Outlook and click on File.
• Expand Account Settings and click on Account Settings…

• There, select your POP3/IMAP account.

• Hit the ‘Change’ option.
• And then go to More Settings.
• Open the Advanced Tab.
• You will see a Server Timeout slider, adjust the slide to increase the Server timeout.

#4. Check Other factors

Other causes for “Outlook sending 2 copies of every email” can be Outlook Synchronization Errors, Corrupt Emails, incorrect rules configuration, or enabling ‘Don’t save copies of saved items’. You can also fix these issues and check if Outlook is still creating duplicates or not.

These methods are some of the solutions and changes that you should make if you encounter an “Outlook is sending multiple copies of an email” issue. But it’s not that hard and fast that it will fix the problem. However, if you are unable to manage emails because of duplicates, you can delete duplicate emails. But, if you have many duplicates then it is not possible to delete all the duplicates manually.
