Problem with icloud email synchronsing.

I have finally managed to get my icloud email address working again in Outlook after having to delete the old account and reinstall it. I had to do it manually because icloud refused to it properly and I kept getting asked for my password which I know was correct. Now Now icloud won't synchronise with the email account. It tells me, incorrectly, after ticking the box next to Mail, contacts, calendar etc that I don't have a default account associated with Outlook. I've checked |Outlook and I do have a default profile. What is going on? Why is Apple's email such a pain to set up in Outlook? The settings are not standard - it drives you mad.
