I have used Deja Office for a couple of years on a Droid phone. I got an iPhone 6 recently and wanted the same functionality. I had some difficulties due to my incorrectly uninstalling iCloud. The Deja Cloud support person was FANTASTIC. My PC and my iPhone now both have clean data and the synch process works flawlessly. The app for the iPhone is even better than the Droid app. I highly recommend this app for those wanting to synch Outlook data between a PC and their iPhone.
