Android does not include a suitable built-in task list, so you’ll need third-party app. Currently, Priacta recommends NitroDesk Touchdown (www.nitrodesk.com). This requires Exchange Server.

If you don’t want Exchange, try DejaOffice with CompanionLink (www.companionlink.com/android/outlook). This is a new recommendation, not heavily tested by Priacta, so please leave comments below to tell everyone how it works for you.
