How to Disable Outlook’s Junk Email Filter

If you prefer to use a third party spam filter, you might want to disable Outlooks integrated filter.

Outlook has a “No Automatic Filtering setting” in Junk Email Options. This turns off all junk filters but leaves the “Blocked Senders List” applied to incoming email. Some people complain that after setting the filter continues to to “No Automatic Filtering” and leaving the “Blocked Senders List” empty, the filter continues to work. Luckily, there’s a registry key that will disable the Junk filter in Outlook (2007, 2010, and 2013). This key will completely disable the junk filter, including the Blocked list, and disable the Junk email options button. It will not affect third party spam filters. Also the Junk button will be grayed out.

To disable the filter, browse to the following registry key and add the DisableAntiSpam DWORD, setting it to a value of 1. If the key does not exist, you’ll need to create it.

• Outlook 2007 HKEY_CURRENT_USER\Software\Policies\Microsoft\office\12.0\outlook
• Outlook 2010 HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook
• Outlook 2013 HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook
