Microsoft Outlook is one of the most popular applications for managing emails, calendars, and contacts. However, your contacts folder is susceptible to becoming messy with duplicates over time. This generally happens when you have imported contacts from multiple accounts, synchronized with smartphones or mobile devices, or restored contacts from backup files. Duplicate contacts not only clutter your address book but also cost time when trying to find the correct person. Fortunately, Outlook offers you the choice of manual or automatic remedies to fix the matter.
In this blog, we are going to discuss the manual method to remove duplicates, and later introduce you to a professional solution, the Duplicate Remover tool.
Why Do Duplicate Contacts Appear in Outlook?
There are many reasons duplicates might appear in your Outlook address book:
- You experienced synchronization errors between system devices and Outlook.
- You imported duplicate PST files multiple times without checking duplicates.
- You deleted accounts that had overlapping contacts.
- You restored old backups, which brought in the contacts again.
No matter how the duplicates appeared, removing duplicates in Outlook is vitally important for maintaining a clean and organized list of contacts.
Manual Method to Remove Duplicate Contacts:
If you only have a few duplicates, it is possible to use Outlook built-in features to clean them up manually.
Step 1: Change to List View
- Open Outlook and select People (Contacts).
- In the row of View, select Change View, and then select System or List.
- This view enables an easier side-by-side comparison of contacts.
Step 2: Survey Duplicates
- Scroll down your list to determine if you see numerous names, phone numbers, or emails that are the same.
- You can also use the Search bar above your contacts to see multiple duplicates of the same contact.
Step 3: Delete Contacts
- Open each duplicate in order to compare the information listed.
- If one contact does not have fields completed, copy the information into the complete contact.
- Right-click on the duplicate contact and select Delete Contact.
