Simply awful. Bombarded with ads, inundated with spam (even with super high security filters and custom spam filters). I finally gave up on it after years of having an account when they began requiring a fee to use it with various pop mail programs like Outlook. I've since switched over to gmail, and while not as polished looking, I've been much happier with the spam filters, lack of obnoxious flashing ads and overall simplicity. Hotmail now is my designated junk mail address.
