I created the TMG Outlook Anywhere rule as per http://www.microsoft.com/en-us/download/details.aspx?id=8946 and also a OWA TMG rule all on the same listener with FBA 

When i start Outlook 2013 on my home pc (non-domain joined) and add an account and fill in the Outlook Wizard my name and mail erik@contoso.com with password i click next and i receive error 

Looking on TMG error&logs i see:
