I read all the postings. I was able to follow the directions and fix the problem. I can now get access to OWA for my email.
Under my CAC card in keychain I right cliked (control-click) and then added the
https://mail.fe.navy.mil for the address. It shows up in your login. Just scroll down and it will be listed alphabetically https:....
That still did not do it. Then in went into system/library/keychains and copied the X509 file. I then went to library/keychains and pasted the file there. I then restarted the computer. I logged in the first time and it asked me to choose a certificate and I chose one of the few selected.
It then prompted me for my CAC password. It worked. I tried it a few times.
I still cant get into flight weather briefer.

So if anyone has any ideas, I am willing to give it a go.
It seems the main problems is having the webpage prompt your computer for a CAC password.
