How to Block an E-Mail in Microsoft Outlook

Prevent specific people from sending you unwanted emails by adding their email addresses to the Blocked Senders list in Microsoft Outlook 2013. Outlook does not notify the sender when you add his email to the list. You can use the Blocked Senders list to get rid of spammers, too. The software moves all new emails originating from that email address to the Junk E-mail folder as soon as it receives them. You can move received emails to the Junk folder yourself and block the sender in the process and you can even block entire domains.

To block an entire domain, blocking all its email addresses at once, type @domain.com or just domain.com and click OK. For example, to block spammer1@sampledomain.com, spammer2@sampledomain.com and spammer3@sampledomain.com, type @sampledomain.com into the field and click OK.
