MS Outlook is a very professional and business-oriented email client that can handle all your emailing, calendaring, contact management, and other needs. But sometimes you may encounter the problem of duplicate contacts in Outlook. This might hamper your system performance, and cause storage errors. It overburdens Outlook and may cause it to crash. Unfortunately, there is no undo process to delete duplicate contacts in Outlook instantly. To eliminate duplicate contacts in Outlook we must first understand the reasons for the issue so that it may be avoided in the future.

Reasons Behind Duplicate Contacts in Outlook

The common reasons why duplicate contacts are created in Outlook are listed so you understand the scenarios and avoid repeating them.

Message moved to the Contacts folder: When you drag email messages to the contacts folder, Outlook creates a new contact for you. It is a big contributor to the formation of duplicate contacts.
Same user with different email address: Another cause of duplicate contact is when a user has multiple email accounts with the same name. As a result, a new contact will be generated for the same individual.
Synchronization of Contacts: To find individuals simply and keep everything synchronized, you synchronize Outlook contacts with your laptop or mobile device and sometimes with social platforms like Facebook messenger, Linkedln, Twitter, and so on, which results in contact duplication.

Remove Duplicate Contacts in Outlook Manually

Manually you can perform the task of deleting duplicate contacts one by one by going through your address book. However, this method requires a significant amount of time and effort but it works, particularly if you have a limited list of contacts and the time to evaluate and fix it.
