e-mails sent from windows live – saved in Outlook drafts as being moved from a different account – told to check spam ?

When I try sending e-mails from windows live - I find it has been stored in my Outlook drafts folder but then informed said e-mail has been transferred from a different account and I need to check my spam settings. Are windows live and Outlook not supposed to be linked if not does anyone know how to link them in relation to new e-mails which I am not sending from Outlook ?
