Hi
I am in the middle of upgrading from Exchange 2003 to Exchange 2013, via Exchange 2010.
I am trying to plan Exchange 2010 so I don't make any mistakes which will cause me grief when I migrate to 2013.
I have setup a workgroup ISA for our small number of Outlook Anywhere users for 2010 and now realise I cannot use NTLM authentication as it needs to be domain joined for Kerberos constrained delegation.
What I am wondering, with 2013 and the fact that all internal users must use Outlook Anywhere, can I configure external users to use basic authentication and internal users to use NTLM authentication (i.e. no username/password prompt?).
At the moment I can only enable Outlook Anywhere and select basic or NTLM authentication so I suspect I can only choose one or the other.
Kind Regards
Steven
