Everything was working fine when I used iTunes to sync my PC-based calendar to my iPad, but then I tried using iCloud, and now my iPad can't sync to my Outlook 2007 calendar. I downloaded iCloud Control Panel, and am able to get the iPad to sync with iCloud. My iPad runs iOS5 and iTunes runs 10.5. My PC runs Windows 7. But I can no longer get the iPad or iCloud to sync with Outlook. I can get the iCloud Calender to show up in Outlook, but the changes I make in Outlook are not reflected in iCloud or on my iPad. (Changes I make to iCal on my iPad are reflected in iCloud, but not in Outlook.) Also, I can see my Outlook calendar on my iPad, just can't make changes to it. Plus, I've got duplicate entries on all 3 platforms: Outlook, iCloud and iPad. This is a mess.
