Saving contacts to your device allows new calls and text messages to be linked with your existing Outlook contacts. You can also see their contact information in your device's Contacts app.
Saved contacts will be added under the contacts in your iCloud account. These contacts will sync to all devices which are signed in with the same iCloud account. We only allow users to export contacts from one device at a time.
If you have contact-export enabled on both iPad and iPhone one will need to be disabled so that we are able to manage conflicts. Duplicates can take up to 24 hours to be reconciled.
