Windows Live Mail

I have not been able to send mail from Live Mail for quite some time now (long before it became Outlook and whatever other names it has been), so I use a different, more reliable server instead. However, when a link sends me to Live Mail, it would be handy to answer it from there. But I keep getting a message that I can't send or receive mail, so, at the moment, I have several messages "stuck" there because they would not go out. Can anyone tell me how to delete those "stuck" messages? I've also tried reporting malicious mail to the address suggested by Support, but that's useless as well. Thanks to anyone who can give me a few answers here.
