Block or unblock senders in Outlook

Messages from addresses or domain names in the Blocked Senders List are always treated as junk. Classic 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.

To add names to the Blocked Senders List:

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

2. On the Blocked Senders tab, click Add.
   
   

3. In the Enter an e-mail address or Internet domain name to be added to the list box, enter the name or address that you want to add. For example, you can add :

   • a specific email address, such as someone@example.com

   • an Internet domain, such as @example.com, or example.com.

4. Click OK and repeat for each entry that you want to add.

   Notes: 

   • If you have existing lists of safe names and addresses, you can move that information into Outlook. Click Import from File and browse for the list file that you want. To create a file that uses your current list, click Export to File and then specify where you want the new file saved.

   • To change a name on the list, click the name that you want to change and then click Edit. To remove a name, click the name that you want and then click Remove.

   • 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 classic 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.

To add a person to the Safe Senders List, click a message from the sender. On the Home tab, in the Delete group, click Junk, and then click Never Block Sender.

To add a specific address or domain to the Safe Recipients List, click a message from the sender. On the Home tab, in the Delete group, click Junk, and then click Never Block the Group or Mailing List.

To manually add names or domains to these lists, do the following:

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

2. Do one of the following:

   • To add safe senders, on the Safe Senders tab, click Add.

   • To add safe recipients, on the Safe Recipients tab, click Add.
     
     

3. In the Enter an e-mail address or Internet domain name to be added to the list box, enter the name or address that you want to add. For example, you can add :

   • a specific email address, such as someone@example.com

   • an Internet domain, such as @example.com, or example.com.

4. Click OK and repeat for each entry that you want to add.

   • If you want all Contacts to be considered safe senders, select the Also trust e-mail from my Contacts check box in the Safe Senders tab.

   • Some people whom you correspond to might not be listed in your Contacts. If you want all such people to be considered as safe senders, select the Automatically add people I e-mail to the Safe Senders List check box.

   • If you have existing lists of safe names and addresses, you can move that information into classic Outlook. Click Import from File and browse for the list file that you want. To create a file that uses your current list, click Export to File and then specify where you want the new file saved.

   • To change a name on either list, click the name that you want to change and then click Edit. To remove a name, click the name that you want and then click Remove.

   • If you are using a Microsoft Exchange Server 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.

You may find unwanted email messages come from particular countries/regions. Classic 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.

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

2. On the International tab, click Blocked Top-Level Domain List.

   

3. In the list, select the check box for the country/region code that you want to block, or click Select All.

4. Click OK in both open dialog boxes..

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.

2. On the International tab, click Blocked Encodings List.

   

3. In the list, click the language encoding that you want to block, or click Select All.

4. Click OK in both open dialog boxes

   Notes: 

   • Unicode encodings aren’t included in the Blocked Encodings List.

   • Messages that have unknown or unspecified encodings are subject to filtering by the regular Junk Email Filter.
