13. A LOT of people are being prompted to enter their CAC PIN many times when visiting Outlook Web App (aka web mail). I am receiving emails from people in the Army, Navy, Air Force, and Marines. I am also hearing it is affecting both Mac and Windows computers. My only solution right now is to use Google Chrome or Opera web browser instead of Internet Explorer / Safari. People who send / receive encrypted emails in Windows will lose this capability. My thoughts are to use Chrome / Opera for the majority of your email.  You will still be prompted a few times when using Chrome / Opera. Then when you absolutely must send / read and encrypted email, enter your CAC PIN the 1-2 dozen times until it finally lets you in.'
