You can use Outlook to block and unblock email addresses. When you add an email address or domain to your blocked senders list, Outlook will automatically move messages from that sender to the Junk Email folder.

Make sure you block the email or domain using the mailbox you received their email from.

If you are setting up blocks for shared accounts, use the Outlook Web App.
