- Check with your administrator for account settings and other requirements (such as VPN).
- When you set up a CardDAV account, your account contacts are synced with iPhone over the air. You may also be able to search for contacts on your organizations CardDAV server.
- Set up an LDAP or CardDAV account: Go to Settings > Mail, Contacts, Calendars, then tap Add Account. Tap Other.
