Windows Phone 101: How to Link Contacts (Video)
You can add a bunch of different accounts to your Windows Phone device in order to pull in contacts from all the different service including LinkedIn, Twitter, Facebook, etc. Sometimes though it’ll end up making duplicates because it can’t tell which contacts are actually the same people from different networks. If it does that, you can manually link your contacts using the following procedure.
1. Click on People.
2. Locate the contact you want to link.
3. Tap the chainlink icon at the bottom of the contact screen.
4. Tap any other contacts you want to link that person to.
5. Repeat as necessary.
