    It depends on what type of duplicate contacts you have, what caused them in the first place. My point is that, "An ounce of prevention is worth more than a pound of cure".

    In my case, I used 'outlook-android sync' app but got un-deletable duplicates for every WhatsApp match. The problem was probably caused by a write-lock conflict between the outlook sync app & WhatsApp Messenger trying to do its own sync as soon as the new contacts appeared.

    Steps to get around the conflict:
    1) Wipe the Contacts Store data so I could start from fresh - see my instructions in thread titled: "Deleting Contacts".
    2) Disable WhatsApp from syncing with contacts, both from account control & using privacy guard to temporarily remove update permissions to Contacts data - ask if you need detailed instructions.
    3) Reboot > run outlook-android sync > reboot > restore WhatsApp sync & write permissions > force a WhatsApp re-sync > check results in Contacts

    You can manage dupes through google contacts. It's how I deal with most iUsers when they move to android and have manually started re-entering their contacts and I'm like "wait! there is a much easier way!"

    Replying to oojafink (with apologies for getting out-of-thread):

    Agreed... use the tools already provided by the supplier of the operating system & contacts app themselves. However, there are trade-offs. The key disadvantage is that you put the security of your private data in others' hands. If a nation state decided to hack google they might succeed (while Sony is not a technology company like google, the prize to the hackers would be huge and so justify the greater effort. I personally do not want google to have all my private data & use other tools from play store, as suggested earlier, to keep my private data on my device & safely encrypted locally under my control.

    It's a choice: convenience vs. data security.

    Hey Tanm1000, I had similar problem. I ended up using Mergix app. Would really recommend to google it. What I liked most is that there is an option to review contacts before the merge. Also no install was required.

    For me, I store and sync all my contacts with google.

    And the most easy way is to go from PC to gmail, contacts, merge duplicats.

    After that all my contacts are sync to my phone as they should.

    Google has a Contacts Preview. Can't remember how I signed up for it off the top of my head, but it's found here: https://contacts.google.com/u/0/preview/all

    The find duplicates feature in this release is amazing and helped me quickly clean up my contacts.

    To remove duplicate items from your Outlook PST file, you can try an easy manual trick. Also, you can avoid receiving duplicate items in your PST files. Most of the time, people recommend you third-party paid solutions. But instead of purchasing such paid professional tools, you can try the easy manual trick shared in the blog post linked below:

    Smart Way to Remove Outlook Duplicates with Ease | N. Sem's Blog

    I hope this would be helpful for you. Must use the manual trick before you can try any paid software. If it fails, then you can take help of such professional solution.

    Thanks and best regards.

    I would like to suggest Shoviv Outlook Duplicate Remover Software to remove duplicate in MS Outlook. The tool for removing duplicate data from Outlook PST files amazingly works for batch operation. It simply allows you to use it for removal of duplicate emails, attachments, calendars, contacts, notes etc from multiple folders of Outlook at one go without slowing down the performance.
