Applies to Microsoft Outlook 2007 and newer

Outlook has a No Automatic Filtering setting in Junk Email Options, which turns off all junk filters but leaves the Blocked Senders List applied to incoming email.

Junk email settings

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.

Before disabling the Junk Email Filter, see Dave’s comment below.

For those users who want to disable Outlook’s Junk email 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.

Disabled Junk mail filter in Outlook 2013When the registry key is set, the Junk button will be grayed out, as seen in this screenshot.

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


Outlook 2007:


Registry editor

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.

    The folder is named Spam? That is not an Outlook folder - you have an add-in (usually install by your antivirus suite) that created the folder and is moving the mail to that folder. Disable the addin in Trust center (File, Options in Outlook 2010, or Tools, Trust Center in Outlook 2007)

    • Fiona says

      Diane, your forum is so useful. I have been trying to solve this problem for ages - that so many legit emails go into my SPAM box despite changing the Junk settings in Outlook. I have followed your advice to go to the Trust Center - can you advise what I do once I'm in the Trust Center - I'm not sure what to do! Thank you!

    • Diane Poremsky says

      You want to check the Addins - do you have an antivirus or antispam addin listed? (Addins is on the Options list in some versions.)

      What does the infobar bar say? Look at the message in the Junk folder and under the subject line, before the message body, is a bar that will say if outlook moved it or if something else moved it (but not what the 'something else' is.)

  2. Dave Offutt says

    We use Outlook 2010 and don't want to totally disable Junk Mail Filtering. However we are very frustrated that in spite of the fact we have extensive ilsts of both "Safe Senders" and "Safe Receipients" the filter continues to send the emails to Junk Mail. This causes a tremendoue amout of wasted time having to carefully comb the Junk Mail for ligitimate Client emails.

    Is there any way to fix this, short of totally disabling it?

  3. Martin Zhou says

    Diane, the junk e-mail protection level options (No Automatic filtering, low, high, safe list only)in my 2010 outlook are all greyed out. I used to be able to make the choice. Thanks

    • Diane Poremsky says

      This is a home computer? What type of email account?
      Try closing outlook then right click on the shortcut and start it using Run as Administrator. Are they enabled now?

      If not a home computer, the admin could have a policy in place.

  4. superarr says

    My drill down in the registry did not reveal the labels that you proposed we change. The only thing I have at that location is the Calendar folder

    • Diane Poremsky says

      If the keys don't exist, you need to create them - outlook doesn't create keys for the default settings.

  5. Rookie says

    Thanks for the article Diane, but I am still having some issues with emails going into my junk mail folder. I have done everything I can think can but am still having emails go into the junk mail folder in Outlook 2010.

    List of things tried:
    Turned off automatic filtering in OWA and Outlook
    Reinstalled outlook
    ran scan\repaired on the .pst
    Disabled filtering on exchange for user
    deleted stale rules via mfcmapi (this worked for about 24 hours)
    Tried this registry addition turning off junk mail folder.

    And I am still getting Junk mail! Help! FYI - most of the junk is actually coming from our own domain and it is only happening for 1 user.

    Any help is greatly appreciated!

    • Diane Poremsky says

      Does the infobar on messages in the junk folder say if outlook moved the message? Do you use an antispam addins? If you use the registry key to disable spam scanning, the mail is getting moved by something else - either an addin on the local computer or the Exchange server.

  6. Paul Williams says

    Good morning Diana

    I'm using Outlook 2010 with Windows 8 and I can't stop it putting files into Junk email, even though I have it turned off. I've tried your "Do it for me" file, but all I get is a Notepad file. I can't find any way to edit the registry.



    • Diane Poremsky says

      You need to right click and save the do it file and choose Save link as - then change the extension to .reg. IE's default setting is to offer to download them but Chrome & Firefox always open the reg files as text files in the browser window, rather than opening it as a reg file or making you save it.

  7. Donna says

    I have Outlook 7 and I am having the same problems with junk mail.
    I have tried everthig I have read here and nothing works. I have very important emails going to junk and is marked spam.

    • Diane Poremsky says

      By marked spam, do you mean the subject had something like [spam] added? An add-in or your mail server is doing that, not outlook. If outlook is moving them, when you look at the message in the juk mail folder, the infobar will say outlook did it.

  8. Jerry says

    hi Diane,

    could you explain more details about why outlook junk mail feature still working after set no automatic filtering? is it a bug so we need to disable it in registry?

    • Diane Poremsky says

      When its on no automatic filtering, the safe and blocked lists still work. The key disables the safe & blocked list. There seems to be a bug where the no automatic folder setting doesn't 'take' - i'm never quite sure if its user error or a bug or something else (like 3rd party software causing problems). The reg key puts an end to all problems and guarantees it won't be turned on accidentally,

  9. jb says

    Hi Diane. Thank you for your wonderful site and for this solution in particular. I've been a Slipstick reader since the late 1990s - I think I remember when Sue Mosher published her first book and used to subscribe to her email list!

    I have Outlook 2010 on Windows 8.1. I retrieve my email via pop/smtp. This is a new installation on a new OS - my hard drive with Vista finally gave up the ghost. I mention that because I didn't have this problem with this same installation on Vista. I'll add that I had a backup of my pst from vista and am using the same one now.

    I too was having the problem of messages being sent to junk mail even though I had that feature disabled, and yes it was Outlook sending them there. So I ran your registry script and the problem went away!

    The problem now is that images in messages aren't displayed - even images for those in my safe sender's list. In an email, I get the info at the top of the message where I can choose to display images, add sender to safe senders, etc. But no matter what I try, I still can't see the images.

    I assume this is because the registry hack prevents Outlook from accessing safe senders data. Does that compute?

    So I reversed the hack and now I can see images. But I'm guessing the Junk folder will start filling up again eventually. Any suggestions? Thanks!

    • Diane Poremsky says

      Yeah, with the registry key set, the safe senders list is not used, so you need to either show all external content or allow it one by one. That setting shouldn't prevent you from seeing the external content if you choose download external content - I'll have to check that.

      If you set the junk mail setting to low or no filtering, does it still move a lot of mail to the junk folder?

  10. jb says

    I got it! I found the solution on another blog (not sure if you want me to credit it here so I respectfully won't).

    It's a problem for people who have multiple email accounts. I have 6.

    Outlook does Junk filtering on a per-account basis.Here's what you have to do:
    1. Go to account settings and set a different address as default
    2. Disable Junk filtering
    3. Repeat steps 1 and 2 until you've set it for every account, then set whichever one you want as default again.

    A bit tedious, but it took me less than 5 minutes. And works!


  11. Gregg says

    Is it possible to do the same thing with Outlook 2003? I tried adding the regkey to: HKEY_CURRENT_USERSoftwarePoliciesMicrosoftoffice11.0outlook but it hasn't worked. Many thanks!

  12. ITDawg says

    Diane, We are new to Exchange and we continue to return to your site for quick, insightful information straight to the point.. .and for that, we THANK YOU!

    I have one question related to this registry key. Often, applications will look in the HKEY_LOCAL_MACHINE hive if it does not find the entry in the Current User hive, therefore allowing a single entry to provide the setting for all users of the machine. I did try adding the key to HKEY_LOCAL_MACHINE\software\Policies\Microsoft\office\15.0\outlook however, it did not affect the Junk feature. Therefore, my question is do you know of a way that a single registry entry will turn this off?


    • Diane Poremsky says

      I know outlook would need to be restarted, but I'm not sure if windows would need to be logged off or restarted.

      You can set the policy keys using a logon script or by using group policy - if you aren't logging into a domain, you can use a local group policy to apply it to all users of the computer.

  13. Dave Birren says

    Thank you! The registry entry (under HKEY...Policies) didn't exist, so I followed the "Do It For Me" instructions and it worked. Finally!

  14. Kay Goon says

    All my emails are going into the junkmail folder. I've tried to follow instructions from the website but am very confused. Are there simple step by step instructions to help someone who isn't very savvy with computers?

    • Diane Poremsky says

      What type of email account do you use? POP3, IMAP, or Exchange server
      Do you use a smartphone to read your email?

      The problem is probably not that you need to disable the junk filter but that something else is causing the problem.

  15. Dave Birren says

    After turning Outlook's junk e-mail filer off via the registry mod noted above, the filtering continued. It wasn't quite as bad as before, but almost. After a while it occurred to me that Avast! also has a spam filter. I turned that feature's setting from medium to low filtering but I still got messages in the Junk folder. So I turned it off and turned the Outlook junk feature back on. Now it's working correctly.

    So check any anti-spam program you may have running. It could be the cause. And if you can edit the way that program labels what it calls spam (however it modifies the message's subject line), you'll know if it's the culprit.

  16. Shirley Kennett says

    Thanks, Diane, for your suggestion on another forum that if the registry key does not exist, go ahead and create it. This worked perfectly for me, has grayed out the junk email options, and nothing has been sent to my Junk folder--exactly as I wanted.

  17. Gav says

    Hi Diane, Is there way if we can use Group policy to disable the junk e-mail button. Will it disable any rule as well which they would have created in the past related to junk e-mail?

    • Diane Poremsky says

      You can. It's in the admin templates under Outlook > Outlook Options > Preferences > Junk Email. It's called Hide Junk Mail UI. It disables all client side filtering, including blocked list. It won't disable Rules in the Rules Wizard. If you want to allow the use of Blocked lists, set junk mail to no protection under Junk mail protection level policy.

  18. Mike says

    Hello all,

    The Registry Hacks (Uh... "modifications") described MUST be done from an Admin account AND NO USER ACCOUNT can be logged into at the time. I'll paint a picture of what I did to myself. Outlook 2010 on Win 7 Ultimate x64. One Admin account and one User account on the machine. I entered the modifications manually and did not use the "Do it for me" provided above.

    1) I "switched users" to the Admin Account while leaving the User Account logged in because a new Key couldn't be created in Regedit as a User due to User lack of permissions. It cried that it "Cannot create key: You do not have the requisite permissions to create an new key under Microsoft". Fine, thus I switched to Admin.
    2) I used Regedit and built the Keys and Data necessary for the Hack while logged in as Admin.
    3) I logged out of Admin and logged back to the User Account.

    In other words, I left the User logged in and it has consequences. The Outlook Junk button 0/1 switch in the Registry Hack worked fine when logged into the Admin Account. The button was available when set to 0 and greyed out when set to 1. BUT when logged in as a User the Junk button was always available. Further, the "office/14.0/outlook" Keys and "DisableAntiSpam" Data that I had entered as an Admin WERE NOT THERE when Regedit was run as a User. They WERE there when logged in as Admin. Something MS-Security-Wise may be going on for the Keys to not be either displayed in Regedit or functional to the User account. I suspect that even though the Hack was applied while running as an Admin, the fact the Registry was open due to the User being logged in prevented the update to the HKCU hive for that User.

    1) The Hack was not functional as a User nor was it shown in Regedit while logged in as a User.
    2) The hack worked fine when logged in as an Admin.
    3) While logged in as a User, I ran an elevated (Administrative) DOS box and entered "Regedit" as the command. Regedit came up and showed the Hack Keys and Data properly. When running Regedit as a User, the Keys and Data were not there.

    There are several fixes available, some more "complicated" than others. In my humble opinion the easiest fix is this:

    The Problem:
    1) When logged in as an Admin the Hack is showing properly in the Registry and worked, but not as a User. In fact the Keys and Data entered as an Admin don't even show up in the Registry (using Regedit) when logged in as a User.
    2) The User account can't edit the Registry to add the Keys and Data.

    The FIX:
    1) Make the User an Admin
    2) Log Out
    3) Log back in
    4) Add the Keys and Data for the Hack using Regedit (it is now happy to manipulate the "Policies" Key)
    5) Make the User a User again
    6) Log Out
    7) Log back in

    Now, when logged in as a User, the modifications are present in the Registry and Outlook will do what the Registry says to do; Disable the Junk button when set to a 1 and enable it when set to 0. THERE IS A CAVEAT that you need to be aware of. If you're logged in as an Admin, you are able to toggle the switch in the Registry at will (kill Outlook first) and when Outlook is started again, the change you made is reflected. BUT if you're logged in as a User, you can't. You have to jump through the hoop in the FIX above in order to toggle from 0 to 1 using Regedit. THE ADMIN REGISTRY SELECTION (0 or 1) WILL NOT AFFECT THE STATE OF THE USER REGISTRY SETTING. This all appears to have happened BECAUSE the User Account was logged in when the Hack was entered into the Registry in the first place (again, using Fast User Switching to get to the Admin Account in order to add the Hack). Making changes to that Key's Data as an Admin doesn't propagate to the Users HKCU hive.

    The best medicine is preventative medicine here. Make CERTAIN that no User Account is logged in when making Registry changes as an Admin. This behavior MAY be isolated to the "Policies" Key path involved because of the Security ramifications of that particular Key. One is able to create other Keys in Regedit under HKCU while logged in as a User. I don't know what happens if the User logs off first to get to the Admin Account or if the problem or FIX above affects only logged on Users, or all Users, or if the FIX has to potentially be applied to EVERY User account on the machine on an individual basis should this happen to you. That paints an ugly picture if this were to happen in an Enterprise environment. I do know what happens if a User IS logged in while using Fast User Switching to get to the Admin Account to apply the modifications. Maybe someone has further insight?

    I'm running Outlook 2007 and recently the junk mail filter went into a comma and stopped working. Every incoming email even those from blocked email land in my inbox. I don't recall changing any setting though.

    • Diane PoremskyDiane Poremsky says

      is the filter still enabled? Was it changed to low? What type of email account are you using? Do you have a contact for yourself and if so, are you trusting all contacts?

  20. pctech says

    I tried this fix in Outlook 2013 with Exchange environment. Spam filtering was disabled in Exchange. The Junk email folder and options became grayed out but emails are still going into Junk. Is there any way to disable it permanently and force all emails to go into inbox?
