The free Hotmail account will no longer work with Outlook.
If I remember rightly a figure of about £12.00 is required to open yourself up to the biggest Spam-fest in the business.
Don't get me wrong, I use Hotmail, but the levels of spam in it's system is huge and their filters only get about 2/3rd of it. You also have to check the spam folder anyway, just to see if anything has been incorrectly assigned.
I reckon it's less hastle to leave the lot on line.
