All seemed well until Office 2013 and iTunes 11 met. Now, nothing works. Neither Contacts nor Calendar syncing works. I reverted back to iTunes v10.x, which got Contacts syncing. But the Calendar still wouldn't. Then I added an Exchange account to the multiple Outlook mail accounts I had and nothing works again.
Seems this is a common issue that spans multiple versions of both Outlook and iTunes that neither Microsoft nor Apple seem keen on fixing. None of the (lame) suggestions on the Apple support site work. Would appreciate a fix!
