SIPRNet Email to Migrate

PETERSON AIR FORCE BASE, Colo. -- Starting Oct 15th, Peterson Air Force Base will migrate the Air Force-owned SIPRNet email services to a cloud-like DoD Enterprise Email (DEE) - SIPRNet provided by DISA. This migration provides significant operational efficiencies, reduces cost and modernizes infrastructure. The 21st Communications Squadron will facilitate the migration for Peterson AFB personnel. Below is some additional information:

· What is DEE?
DEE provides SIPRNet email capabilities to all DoD entities via a common platform. You will continue to be able to locate, email and collaborate with any DoD member who has a SIPRNet email account.
· How does this affect my ability to execute the mission?
Your SIPRNet mission will continue through the migration. It's important to remember this is strictly a change in your SIPRNet email service provider. There will be no change to your current SIPRNet equipment or how you access your SIPRNet workstation. The procedures, data and access that you have today will continue once migrated to DEE.

· What will happen to my current SIPRNet e-mails?
Your current email will be preserved as part of the migration. You will be required to reduce your mailbox to 50MB prior to the DEE migration. This is accomplished by archiving to a .pst file (please contact your information assurance officers for assistance). Once migration of your account is complete you will be able to re-attach and upload your .pst files to your DEE account.

· What will I need to do to facilitate my SIPRNet email migration?
Aside from reducing your mailbox to 50MB, please go to milConnect at and update your organization, location and Office Symbol; to ensure accuracy of the DoD Global Address list. Keeping milConnect updated ensures your SIPR email is regionally hosted near your duty location, thus ensuring timely delivery of email.
