BlackBerries never sync - they reconcile. The difference being that once an email is sent to your BlackBerry, it will never be sent again. Actions like marking emails as Read/Unread and Deletes are dealt with individually. Synchronization - like Microsoft ActiveSync - requires resynchronizing the entire mailbox periodically which eats up battery life and costs data useage when applicable (typically abroad when it costs a LOT!).
That said, yes, Windows Live Mail and MSN mail are both supported.
