Some features aren't available in all countries. Access to some services is limited to 10 devices.

1. You can buy iWork for iOS and iWork for Mac from the App Store if they didn't come free with your iOS device or Mac. 
2. Outlook 2010 Personal Edition and Outlook Click-to-Run installations aren't supported.
3. iTunes in the Cloud availability for music, movies, and TV shows varies by country. Previous purchases may be unavailable if they are no longer in the iTunes Store, App Store, or iBooks Store. Not all previously purchased movies are available for downloading to your other devices.
4. If you have two-factor authentication and you use iCloud Keychain, you'll need iOS 9 and OS X El Capitan.
5. If you don’t meet the minimum system requirements, your data is still protected by two-step verification. However, if you change your Apple ID password while you're signed in to iCloud on devices that don't meet the minimum requirements, you might see these issues.
