To get rid of duplicates in Outlook, you can either use the CubexSoft Outlook Duplicate Remover right away or try some manual methods first.

Reasons for Deleting Duplicate Contacts in Outlook

Here is a list of typical reasons why Outlook might have duplicate contacts. You can take precautions to stop these situations from happening again by being aware of this possibility.

• Message dragged to Contacts folder: Dragging email messages into the Contacts folder in Outlook can result in the unintentional creation of new contacts, which is a major factor in the duplicate contact issue.
• The same person using multiple email accounts: Using multiple email accounts bearing the same name by one user is another cause of duplicate contact. Thus, the same individual will have a new contact created for them.
• Contacts Synchronisation: Many users synchronise their Outlook contacts with laptops, mobile devices, and even social media sites like Facebook Messenger, LinkedIn, and Twitter for easy access and synchronisation across devices and platforms. But doing so might unintentionally lead to duplicate contacts.
• Exchange server with multiple address books: This is a situation where a number of organisations have multiple address books.

Manual Approaches to Delete Duplicate Contacts in Outlook

To manually remove duplicate contacts, use one of the two methods listed below, one for single deletions and another for multiple deletions at once:

Method 1. Remove Contacts One by One

1. Launch Outlook and navigate to the People tab.
2. Next, select Views box>>Phone from the Current View option. Here, you can locate all of the duplicates.
3. Press the Ctrl key to select each duplicate contact one at a time in the contact list.
4. Once all duplicates have been chosen, click Delete.

Method 2. Using Export/Import Method

• Launch Outlook and select the People tab.
• Right-click on the Contacts folder that is currently open, then choose New Folder and Rename it.
• Return to the Contacts folder and use (Ctrl+A) to select every contact.
• Using the shortcut key Ctrl+Shift+V, select Move to Folder and then select the new folder to transfer contacts to the new folder. (Drag and drop is another option.)
• Select Import/Export under File>>Open & Export>>.

Note: In Outlook 2010, go straight to step 8 by selecting File >> Open >> Export to remove duplicate contacts.
