I was just looking at an iPhone 4 from one of my users, and I was unable to turn on the backup for notes because it says that I'm not using an iCloud email address.
The user in question already has an iCloud account, and I can log into it with the using http://www.icloud.com/ (which consequently also gives the same message).
Is there a way to get this working? I tried creating a new iCloud email account, but it doesn't seem to like that either, stating that the email is not enabled for an iCloud email account.
