Block a mail sender

Messages from addresses or domain names in the Blocked Senders List are always treated as junk. Outlook moves any detected incoming message from senders in the Blocked Senders List to the Junk E-mail folder, regardless of the content of the message.

To add a specific sender to the Blocked Senders List, click a message from the sender. On the Home tab, in the Delete group, click Junk and then click Block Sender.

   • If you are using a Microsoft Exchange account, all of the names and email addresses that are in your organization's address book — also known as the Global Address List — are automatically considered safe and can’t be added to the blocked list.

By adding email addresses and domain names that you trust to the Safe Senders List, you instruct Outlook that messages from those sources are never to be considered as junk. If you belong to mailing lists or distribution lists, you can add these names to your Safe Recipients List.

You may find unwanted email messages come from particular countries/regions. Outlook lets you block messages from those areas - the Blocked Top-Level Domains List lets you block messages from email addresses that end in a particular top-level domain or country/region code. For example, selecting the CA [Canada], US [United States], and MX [Mexico] check boxes in the list blocks messages that come from email addresses that end in ca, us or mx. Additional country/region codes appear in the list.

You can block all email addresses in language encodings — also known as character sets, or alphabets — that you specify. Today, most junk email is sent in the US-ASCII encoding. The remainder is sent in various international encodings. By using the Blocked Encodings List, you can filter out unwanted email messages that are displayed in languages that you don't understand.

1. On the Home tab, in the Delete group, click the arrow next to Junk, and then click Junk E-mail Options.
