Live.com has blocked my iphone from asking to save passwords on my iphone

My iphone won't save passwords because it says live.com has blocked this ability. Who, what is live.com? How can it make decisions for me? I have to fill in passwords so often it's ruining my iphone experience. I am saving up for a Mac. Microsoft have made things so difficult for me. Apparently I have more than one outlook account, so I cannot use iCloud - but I can't find two? Outlook will not sync to my yahoo mail account because it cannot access my outlook data file. It's very frustrating because there's no clear instructions and I become so confused I give up without using the benefits of my new iphone. Has anyone some clear definite advice please? Please remember that I'm not a computer geek but a person scrambling his way through the maze of mixed messages.
