User Query: I have got around 2,000–3,000 contacts in Outlook, and I’m noticing a lot of duplicates. Cleaning them manually is taking way too long. Is there a quicker way to remove or merge duplicate contacts without losing any details?

The SysInfo Outlook Duplicate Remover is one of the ways that can ease the task for you and save you from the clutter of data.
Below, we have covered two manual methods to remove duplicate contacts. You can follow according to your preference if you are going to tackle this manually.
Manual methods mostly focus on contacts. Handling the task to remove duplicate emails in Outlook at the same time makes things harder. Once everything is set, move all the contacts from the temporary folder back into your main Contacts folder in Microsoft Outlook.

Using a professional tool is always a reliable option for removing duplicate contacts. The SysInfo Outlook Duplicate Remover is specifically designed to eliminate duplicate contacts with ease. It can remove items like emails, contacts, and calendar entries from PST files and save you a lot of time and storage.
