Managing personal Outlook.com account settings, security, and privacy
Your just leading yourself to frustration. You can NOT stop spam from going to your mailbox. Once you accept that fact you'll won't be able to be stress free.
If spam arrives in your Inbox move it to your Junk Folder. That's it. Nothing more to be done.
Spam, just like postal junk mail, is just a way of life now. The ONLY way to escape spam is to NEVER EVER use an email address for anything.
