I cannot 'send' Emails from MS Outlook.  I receive them but can't reply or send original Emails.  This is the error message I received today Nov. 1/13.

The server for account "Gmail" returned the error "5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 s14sm17599944oeo.1 - gsmtp." Your username/password or security settings may be incorrect. Would you like to try re-entering your password?
