Check with your email provider that the settings entered in to Outlook 2013 are correct.  If the account has been working for some time and then starts producing this error, don’t assume that the settings must be correct.  From time to time, email providers will change their servers and settings and the old settings may no longer work.  It has also been reported in the past that by resetting the password at the email providers end can solve the problem for an account that has been working previously.  This is the MOST common reason so don’t skip past this step.
