This Hotmailog.com taught how to block someone’s email from the Inbox of Hotmail (now called “Outlook”). You will need to use the Outlook web page to change the settings because they can not change from within the Outlook Mobile applications.
Creating a Rule:
1: Open the Outlook website. Doing so will open your Inbox if you log on to Outlook.
If you have not already signed in, click sign in Hotmail, enter your email address (or phone number) and your password and click sign in.
