How to update Outlook Address Information

The steps below allow you to update the contact information shown when people find you in the Global Address List (GAL) in Outlook.

Go to https://idco.dmdc.osd.mil/idco/. Select your PIV (Authentication) cert to get into ID Card Office Online. Select “My Profile.”

Choose “My Profile”

Log in (again) using your CAC.

Choose “CAC”, then “Login”

Update your “My Profile,” first to verify your personal email, and family member contact information.

Update your personal email and family member contact information first.

Now update your work information.

Select “MIL” and verify your work information.

The last tab, “MIL” should be reflected in your address in Outlook. The Navy email system is undergoing yet another update. This is a good thing, as the current iteration is badly outdated. However as a result some or all of this post may not apply to you any longer. Historically changing this information could take up to 72 hours before it populated in Outlook, and this may still be true.
