Step 4: Click on Apply / Sync in iTunes. This will transfer the contacts from your PC / Outlook to your iPhone or iPad.
Note: If you are using iCloud to backup your contacts, syncing to your Outlook may create duplicate contacts on your device.
Tips: Scroll down to "Advanced". Here you can set if you want to replace Contacts, Calendars, Mail Accounts and Notes on the iPhone or iPad using the information on your PC. Please choose this carefully, if you have contacts that are not on your Computer but only on your phone, you will lose those contacts if you select this option.
