All Army AKO users who have a CAC should now be migrated to DISA's Enterprise Email this means you will no longer be able to access your AKO webmail.  EEmail requires 100% CAC use from   Please look at this page for EEmail support.


If you are getting ready to retire please check out the 'retiring' page.  I want to make sure you understand you will no longer have access to your Enterprise Email and AKO.


AKO transitions to next-generation enterprise services (3 June 2013)


Is webmail2 stalling while loading?  (Follow this guide, it may help)


Alternate fix


Information from the AKO Single Sign On information page at:  


The requirement for AKO to go 100% CAC is NOT their choice.  They are being mandated by the CIO-G6 (Chief Information Officer - G6) office which is based off of JTF-CNO CTO 07-015 (CAC required), Public Key Infrastructure (PKI) Implementation (specifically Task 10).


If you are receiving a message that AKO is not trusted, you need to update your DoD Certificates


If you have a new CAC and are having problems accessing AKO, update your ActivClient (ActivClient 6.1 users use this link)


Most AKO access problems can be remedied by following these corrections to your Internet Explorer web browser

Watch a video of these steps


Are you having problems accessing AKO now that Microsoft has pushed out Internet Explorer 11 as a critical update?  Please go through this guide again.


I am the content provider for AKO's CAC Reference Center and answer emails for AKO.  Click link: to send email.  Some of the below questions are asked often.


The process of registering your CAC with AKO was removed on 1 May 2011.  This also means dual CAC holders can use either issued CAC.  Read more about it here.



Question 1:  Why can't I log into AKO with my CAC?


Answer 1: Follow the guidance in this PDF.




Question 2:  When I logon to AKO with my CAC, I see my old CAC certificates (or more certificates than just my own) to choose from.  How do I clear the old Certificates?


Answer 2:  Open Internet Explorer, Select Tools, Internet Options, Content (tab), Certificates (button).  Select all of the Certificates you don't want, then select the Remove (button).  You may have to remove them individually.




Question 3:  When attempting to login to AKO; the browser closes (crashes); receive "500 - Internal Server Error" message; returns you to the home screen; or just doesn't seem to work.


Answer 3:  Follow the guidance in this PDF




Question 4: How do I change my AKO password? 


Here's How:  Logon to AKO with your CAC (or without CAC for non CAC-Holders).  Click on: My Account, Account Settings, Change Password.   The rest should be self-explanatory.  AKO does have a self help video located here.  You will need to have Adobe Flash player installed, and be using Internet Explorer to view.  NOTE  I had to download them, open up IE, go to File, open, navigate to my download location and select the .swf file.  It then started to play in my web browser.


NOTE:  Please be aware...  Sometimes when you type in your new password, it will 'look' like you didn't do it right, because it will come back to the same page.   Please scroll to the top of the page where you will see one line of text that will be green for a successful change or red telling you a reason why it did not change.




Question 5:  Can I use Outlook to check my AKO email?


The ability to check AKO via IMAP will diminish in the near future for all personnel who have a CAC as we are being migrated to email.


AKO has their Outlook Connector working with CAC and currently only works with Outlook 2003 & 2007, (not 2010 or 2013).


Answer 5:  Yes you can.  Here is how to set up AKO in Outlook 2007 (with pictures), or Outlook 2010, or any other POP / IMAP email client.  (You can also check your email on your Mobile Phone).  The instructions here are for Outlook 2007 or 2010, but are virtually the same setting for Outlook 2003.  THIS WILL NOT work for Enterprise Email


Answer 5.1:  Set up the AKO White Pages in Outlook (Windows) (watch video).






Question 6:  Can I use Thunderbird to check my AKO email?


Answer 6: Yes you can.  Here is how to set up AKO in Thunderbird




Question 7: Can I decide how my "Friendly name" shows up on AKO?   A friendly name example is:  Danberry, Michael J CW3 MIL USA USARC.


Answer 7:  If you are dual account holder (i.e. you are a civilian and a Reservist) you can select which friendly name is displayed within your AKO webmail. 

  1. Log into your AKO/DKO account.
  2. Click on the ‘My Account’ tab.
  3. Click on ‘Mail Preferences’.
  4. Click on ‘Mail Options’.
  5. Put a check in the box labeled “Reset display name to: [your display name here].
  6. Click on ‘Submit’
  7. Select your display name.
  8. Click on ‘Submit’




Question 8:  "There is a problem with this website security certificate" error.  Your options are listed as  "Click here to close this webpage" or "Continue to this website" where it states it is not recommended.


Answer 8:  Latest DoD Certificates are needed, download and install them here




Question 9:  I am receiving the message: "403 Access Forbidden - You do not have Permission to Access this resource."


Answer 9.1:  Go to: from this link.  There could be a problem with the shortcut in your favorites.  Simply re add AKO to your favorites replacing your existing one.  I also right click and select properties to remove all of the extraneous stuff after  then save.  This helps speed up the load from your favorites.


Answer 9.2:  Follow this PDF for correcting the settings in your Internet Explorer


Answer 9.2:  This could also be caused by your Antivirus / Security Software.  First try disabling it before going to AKO.  You can also uninstall it then restart your computer and see if it works afterwards.  This has been the cure for a few McAfee and Kaspersky users.


Answer 9.2:  ActivClient does not always recognize a CAC if you insert it after you have opened Internet Explorer.  Solution:  Close all Internet Explorer windows, remove your CAC from the reader, re-insert it into the reader, now open Internet Explorer.




Question 10:  Receiving the message:  "You are not logged in with your CAC" when you are actually logged on with your CAC when using Firefox.


Answer 10:  Use Internet Explorer when using your CAC with anything related to AKO (and most DoD sites).


Answer 10.1:  Look at #16 below


Answer 10.2:  Follow this PDF for correcting the settings in your Internet Explorer


Answer 10.3:  If you insist on using Firefox, look at the Firefox page for the required configuration.




Question 11:  When attempting to extract ActivClient 6.1, the icon is not a folder with a zipper on it, or a different program opens up. 


Answer 11:  Somehow your file association was changed on your computer.  Look here for the answer




Question 12:  I have 2 CACs (1 military & 1 civilian or contractor), Am I only able to use one on AKO?


Answer 12:  No, not as of: 1 May 2011 you do not have to manually register your CAC anymore, so, both off them will work on AKO.  Read more




Question 13:  I set up my AKO logon for CAC only. I don't want it this way anymore, how can I change it back?

  1. Log into your AKO/DKO account with your CAC.
  2. Click on the ‘My Account’ tab.
  3. Click on ‘Account Settings’.

Question 15:  While logging into AKO with your CAC, selecting your certificate and typing in your PIN the page stalls at "You will be logged into AKO shortly."


Answer 15:  When the new window pops up showing you are being logged into AKO, make sure or  is NOT in your trusted sites (IE 8, 9, 10, and 11),  Being in trusted sites is only required when using  IE 6 & 7). 

Here's How: Open Internet Explorer Go to Tools, Internet Options, Security (tab), Click on trusted sites (green checkmark), Click Sites (button) now click on and / or and then select Remove, close this window, then click OK.

Answer 24-1:  Visit this website:, select Replace Certificate

NOTE: You have to logon to the site with your CAC.  Visual steps 

NOTE2:  In my tests with Windows 7, it did NOT work with the Windows 7 built in Smart Card utility or with ActivClient installed.  So, you will need to find a Windows Vista or XP computer.


An Air Force Major sent this:  "When I tried to access the CAC User Maintenance Portal on a Windows 7 computer, the Java failed; however, when I tried the same thing on my Windows 7 computer at work (.mil domain), Java still failed but I got a popup dialog that told me I had to use the 64-bit version of IE and Java.  When I started a browser session with the 64-bit IE, I was able to get to the User Maintenance Portal just fine."

2.  Follow the guidance in this PDF to make sure your browser is configured correctly.

3.  Go to:  Tools, Internet Options, Advanced (tab) and click on: Restore advanced settings (button)

4.  If you are using your Favorites to access AKO, try from this direct link:  If this works, it means your AKO link in your favorites is too old.  Once it works, add this new one to your Favorites.

1.  Upgrade to the latest version of Firefox

2.  If you are using your Bookmarks to access AKO, try from this direct link:  If this works, it means your AKO link in your Bookmarks is too old.  Once it works, add this new one to your Bookmarks.
