I´m setting the co-existence environment between Exchange 2007 and Exchange 2013 publishing OWA services throught ISA Server 2006.


For OWA I have FBA just on ISA Server ( NTLM on Delegation Tab) and "Windows Authentication" set on Exchange 2007 OWA virtual directory authentication.


If I left default OWA authentication for Exchange 2013 (FBA).. The internal proxy redirection (between Exchange 2013 - Exchange 2007) in order to access OWA for users not migrated will works?? I assume they get the FBA from Exchange 2013 Client Access and they

will get the Exchange 2007 OWA experience without a second validation. Is this OK?


External users only will get the FBA presented for ISA Server and not double-FBA (1st ISA , 2nd Exchange 2013). Is this correct??
