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), the parent organization for the Army Knowledge Online (AKO), shut down all AKO mailboxes on the NIPRNet and SIPRNet email systems on March 31, 2015.

AKO will continue to forward email for Army Common Access Card (CAC) holders until September 30, 2015.

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 sending email or notifications to AKO email addresses are updated no later than September 30, 2015, to send emails and notifications to DEE (Department of Defense Enterprise Email) email or other authorized email addresses.

The Army established 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 guidance allows the Army to eliminate the legacy AKO email system without impacting the operational force. Before DEE implementation, AKO email was used by Soldiers transitioning from one location to another.  The establishment of DEE eliminates the need for AKO email. Note: This action will not affect access to the AKO portal.

For information on saving/exporting AKO email, refer to the following TTPs, please click the following link: https://esd-crm.csd.disa.mil/app/answers/detail/a_id/88
