Last reviewed on November 18, 2013

Applies to Microsoft Outlook 2013. Outlook 2010, Outlook 2007

Junk email settings Outlook has a “No automatic filtering” setting but the blocked senders list is applied to incoming email.

Some users complain that the filter continues to work after setting it to no automatic filtering and with the blocked list empty. Other users prefer to use a different spam filter.

There is a registry key that will disable the Junk email 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.

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.

In Outlook 2013, open the registry editor and browse to

DWORD: DisableAntiSpam
Value of 1 disables the junk filter, 0 enables it

In Outlook 2010, browse to

Restart Outlook for the registry edit to take effect. The Junk email folder will remain (but should not be created if you make a new default pst file) – you can delete the junk folder using OutlookSpy or MFCMAPI.

To re-enable the Junk filter, edit the reg file in Notepad, replacing the 1 with 0.

To remove the key, Open the registry editor, browse to the value then delete it.
