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 will be migrated to PIV AUTH certificate for Email access. You will no longer use your Email certificate for Enterprise Email.
Mac users who choose to upgrade to Mac OS Catalina (10.15) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm
Accessing OWA requires the installation steps below and an email account on that network

Step 2:CAC Reader driver |

Some differences between OWA (2003) and OWA (2010)
A Windows 10 patch rendered OWA unusable, follow this guide
