The AESD Interactive Voice Response (IVR) system has been simplified to better support customer calls with only three options: AKO SIPR, AKO, and All Others. After customers make their first number selection, an AESD Technician will answer the phone. Contact the Army Enterprise Service Desk at 1-866-335-ARMY (2769) or https://esd-crm.csd.disa.mil/.



The Program Executive Office Enterprise Information Systems (PEO EIS) all mailboxes on the NIPRNet and SIPRNet AKO email systems were shut down on March 31, 2015. AKO continued to forward emails for Army Common Access Card (CAC) holders until June 30, 2015 but no longer supports that process. Although AKO will retain the user@us.army.mil identifier in its directory for use by Single Sign-On applications, all email addressed to @us.army.mil accounts will be returned to the sender once forwarding has ended. PEO EIS will retain existing email records until the appropriate records management determination is made.  All Army application owners should verify that applications that send emails or notifications to AKO email addresses are updated no later than June 30, 2015 to send emails and notifications to DEE email or other email addresses.

This guidance will allow the Army to eliminate the legacy AKO email system without impacting the operational force. AKO emails are being forwarded to other official systems today. Before DEE implementation, AKO email was used by Soldiers while transitioning from one location to another, but DEE accounts now follow Soldiers throughout their careers and eliminates the need for AKO email. Note: This action will not affect access to the AKO portal.

Important Notice for retirees and family members: AKO email access ended on 31 December 2014

On 31 December 2014, forwarding of all retiree and family member Army Knowledge Online (AKO) email to commercial accounts ended. Any messages sent to AKO email addresses will be returned as undeliverable. Portal accounts will remain active for a short additional period.

Because these AKO email accounts are no longer active, retirees and family members should: 

  • Update all accounts and memberships currently using the AKO email address, such as myPay accounts with a commercial address (e.g., .com or .net accounts).
  • Obtain a premium DoD Self-Service Logon (DS Logon) account. This account allows access to personal benefits records and claims on DoD and Department of Veterans Affairs Web sites (click for instructions for creating a DS Logon account).
  • Download any files/data from AKO files they wish to retain.

For additional information, including instruction documents, visit AKO’s Migration Page for Retirees and Family Members at https://www.us.army.mil/suite/page/AKOmigration.

The Army established Army Knowledge Online (AKO) in the late 1990s to provide online information services for U.S. Army personnel, later extending some AKO services to retirees and family members. Services included email, collaboration, discussion forums, a directory, and direct access to many DOD and Veterans Affairs (VA) websites.

The Army is now modernizing the AKO infrastructure and services to become more interoperable across the DoD and to achieve the goals detailed by Secretary McHugh.

This transition follows the Army’s successful migration of 1.4 million email accounts to DoD Enterprise Email (DEE) in July 2013. The next phase includes enterprise services for collaboration, content management, and unified capabilities (including chat, presence, voice and video over IP)—all of which draw upon the authoritative identity service that underpins DEE.

All Army business processes will move off the current AKO platform onto next-generation enterprise services over the course of several years. Only business users will have access to enterprise services. Army military retirees and family members will access DoD online self-service sites, like Tricare and myPay, through DoD Self-Service Logon (DS Logon).

The Army is developing a transition timeline for AKO services and accounts,  to include military and civilian retirees and Army family members. Details will be published in an upcoming Army execution order.
