They talk about one Microsoft Account (MA) to use for everything. My family has six POP3 email accounts with live.com being handled locally by Outlook 2007. We're totally confused about the behavior of MA at the server level, but there is one basic question that would put us on the right track if we had a clean-cut answer: With six different email accounts, are they all supposed to get along together under the same MA, or do we need six different MA's?
