How do you block spam using Microsoft Outlook?

Microsoft Outlook has an excellent feature called the Blocked Sender List.  There are two methods of blocking email by individual email address or by domain.  Often when you receive spam, it is being sent from a variety of email addresses at the same domain.  For example: noreply@luxor23.com, support@luxor23.com, etc.  In these instances, it is better to block the entire domain as opposed to blocking individual email addresses.  Any email from a blocked email address or domain is then automatically sent to your Junk Email Folder.  You can then optionally configure Outlook to automatically delete Junk Email.

Blocking Individual Email Address

1. Click the Microsoft Outlook Inbox so that your Inbox Email is displayed in a list.
   
   
2. Right-mouse click the email that you wish to block.
   
   
3. Select Junk Email.
   
   
4. Select Add sender to Blocked Sender List.

Blocking Entire Email Domain

1. Click Tools.
   
   
2. Click Options.
   
   
3. Click the Junk Email button.
   
   
4. Click the Blocked Senders tab.
   
   
5. Click the Add button.
6. Type the name that you wish to block using the format of  @domain.com.  So for example if you wanted to block all email from luxor23.com, you would type: @luxor23.com
   
   
7. Click OK.
   
   
8. Click OK.
   
   
9. Click OK.
   

Automatically Delete Junk Email

1. Click Tools.
   
   
2. Click Options.
   
   
3. Click the Junk Email button.
   
   
4. Click Permanently Delete Suspected Junk E-mail Instead of Moving It to the Junk E-mail Folder.
   
   
5. Click OK.
   
   
6. Click OK.

It is worth noting that the use of Microsoft Outlook Rules to block incoming email is not recommended.  Microsoft Exchange Server has a very limited amount of storage space for Microsoft Outlook Rules therefore this method quickly becomes ineffective and not at all comprehensive.
