Using New Outlook on Windows for personal email, calendar, and contact management
Having same problem and working with a blind person using JAWS and the only way to get out of the TO, CC, or BCC fields after entering addresses is to bring up the JAWS field list and then use first letter navigation to get to the Subject edit field. Otherwise, you have to address the email after entering a subject and type your email message by using SHIFT TAB back to the TO, CC, or BCC fields.
