Would you like to block Emails from specific people? In Outlook, you can prevent future e-mails from arriving into your inbox from that person’s Email account.
Right-click on the Email one time. This will bring up a listing of options
… choose Junk Email. From there, choose Add Sender to Blocked Senders List.
Outlook also lets you prevent Emails from an entire domain from getting into your inbox. To do so, first open Outlook. Click on the Tools menu, then Options. Choose the Preferences tab, then under Email, click on Junk Email. Click the Blocked Senders tab, then click Add. In the box Enter an Email address or Internet domain name to be added to the list, enter the address you want added, then click OK (the domain would be the "@" sign plus anything that follows it).
You can repeat the process for each name or address that you want to block.
