I use Outlook for mail, calendar and contacts.  For calendar events, it sync's to iCal with sync services.  From there I can sync to my iPhone via iTunes.  I installed Mavericks and immediately noticed in iTunes I could not sync my calendar.  I saw in an online forum you can no longer sync calendar, contacts, bookmarks, etc via iTunes with Mavericks.  This has to go through iCloud which I had previously not used.  I then turned on iCloud on the MacBook Pro and iPhone (i5S).  When I opened iCal none of my calendar events from Outlook had been populated.  Apple Care would help me with only Apple applications.  Although sync services and the sync'ing in iTunes was something Apple removed in Mavericks, they feel this is a MS problem.  I have asked Apple Care to walk me through restoring to Mountain Lion in order to solve my sync problem.  My question to MS - is there a way to continue to use Outlook for these things and get them to sync to Apple products - iPhone and iPad - with Mavericks?
