Duplicate emails in Outlook can quickly clutter your inbox, leading to unnecessary storage use and a less efficient experience. Whether you’re dealing with repetitive notifications, newsletters, or multiple copies from a single sender, removing duplicates is crucial for maintaining an organized inbox. Fortunately, Outlook offers several methods to help you find and delete duplicate emails quickly. In this article, we’ll walk through how to delete duplicate multiple emails in Outlook.

Why Do Duplicate Emails Appear in Outlook?

Before diving into solutions, it’s important to understand why you might encounter duplicate emails in Outlook:

• Server Syncing Issues: Sometimes, a sync issue between your email server and Outlook can cause emails to be downloaded multiple times.
• Imported or Forwarded Emails: If you’ve recently imported emails from another account or forwarded them from a different device, you might end up with duplicates.
• Rules or Filters: Misconfigured email rules or filters may inadvertently cause emails to be received multiple times.

Now, let’s explore different methods to remove these duplicate emails from your Outlook inbox.

Method 1: Use the Clean Up Tool in Outlook

Outlook has a built-in feature called the “Clean Up Tool” that can automatically remove duplicate emails within a folder. Here’s how to use it:

Run Outlook and go to the Folder where you want to remove duplicates

From the Home tab in the ribbon, look for the Clean Up button. You’ll see options for:

• Clean Up Conversation: Removes duplicates within a single conversation.
• Clean Up Folder: Removes duplicates from the entire folder.
• Clean Up Folder & Subfolders: Removes duplicates from the folder and any subfolders.

Select the Clean Up Folder option

Method 2: Use Search to Find Duplicates and Delete Them Manually

If you don’t want to rely on Outlook’s Clean Up tool, you can use the search functionality to find and delete duplicate emails manually. Here’s how:

1.      Open Outlook and navigate to the folder where you suspect duplicates.

2.      Use the search bar at the top to filter emails by certain criteria. For example, you can search by subject, sender, or keywords that are commonly found in the duplicate emails.

3.      Once you have the filtered list, visually scan the results for duplicates.

4.      Select the duplicate emails by holding the Ctrl key and clicking on each duplicate message.

5.      Right-click and choose Delete to remove them from your inbox.
