How Do I Stop Duplicate Emails in Outlook 365?

Outlook 365 can be a powerful tool for managing your emails, but sometimes it can send multiple copies of an email, which can be frustrating and annoying. There are several reasons why this may happen, including the interval time being set too short, antivirus software interfering with Outlook's functionality, and network connection issues.

One common reason for duplicate emails in Outlook is that the interval time between send/receive connections is set too short. This means that Outlook is constantly checking for new emails and sending updates to your contacts, which can result in multiple copies of an email being sent. To fix this issue, you need to adjust the interval time by following these steps:

1. Open MS Outlook and go to the Send/Receive tab.

2. Click on the Show Progress option.

3. Select the Tools tab and click on Send/Receive.

4. Adjust the interval time to a longer period, such as 15 minutes.

Another common reason for duplicate emails is antivirus software integrated with Outlook. If you have antivirus software installed on your computer, it may be interfering with Outlook's functionality and causing multiple copies of an email to be sent. To fix this issue, you can try uninstalling or disabling the antivirus software temporarily to see if it resolves the problem.

In some cases, duplicate emails may also occur due to network connection issues. If you are experiencing problems with your router, Wi-Fi, modem, or other network connection, it may cause multiple copies of an email to be sent. To fix this issue, try resetting your router and modem and see if it resolves the problem.

If you have tried all of these steps and still experiencing duplicate emails in Outlook 365, there may be another underlying issue causing the problem. In that case, we recommend going through our complete blog on fixing Outlook errors to find a solution.
