Disclaimer:  I've received concerns from people about having these links here for the world to see.  Here are my thoughts:  These are all public facing OWA servers that are located in a DMZ on a government computer network and require your CAC to access the site.  So, the links won't help anyone if they don't have a CAC and an email account on that particular network.


Between mid October 2019 and mid February 2020 everyone in the Army was migrated to PIV AUTH certificate for Email access.  You no longer use your Email certificate for Enterprise Email.

Mac users who choose to upgrade to Mac OS Catalina (10.15) (or higher) will need to uninstall all 3rd Party CAC enablers per



Accessing OWA requires the installation steps below and an email account on that network


Installation Steps
Step 1: Obtain a CAC Reader
Step 2: CAC Reader driver
Step 3: DoD Certificates
Step 4: ActivClient
Step 4a: Update ActivClient
Step 5: IE adjustments
Step 6: Find and Click the link below for your OWA Email server and select the EMAIL certificate on your CAC (Except for Dual Persona personnel), you will need to select your PIV certificate if on
Example of selecting Email certificate

Air Force  |  Air National Guard  |  Army  |  Army National Guard  |  Army Reserve  |  Coast Guard  |  Defense Contract Management Agency (DCMA)  |  Department of Defense (DoD)  |  Marines  |  Navy  |  Other Organizations

Some differences between OWA (2003) and OWA (2010)

A Windows 10 patch rendered OWA unusable, follow this guide

Windows 10 users will see the certificate selection differently than previous versions of Windows.
You may need to click More choices to see the additional certificates, once selected, click OK
