Hi James,
If you want to use Integrated auth on the RPC/HTTP site, you'll need to configure the firewall to use Kerberos Constrained Delegation, since if you're using FBA at the firewall's Web listener you can't delegated NTLM, and fallback to basic on that listener will only support basic delegation.

We have:- Two DC's running 2008 with SP2 in the same site as the exchange servers. Two exchange servers running 2007 sp1 update rollup 7. Exchange1 - CAS, Hub Transport Exchange2 - Mailbox using LCR.

I sort of recently tore my hair out over this so I may have some ideas. Rpcping was the tool that led me to discover the fix (which was "officially not required" but "required" ;/). jlc From: James Hill [mailto:james.h...@superamart.com.au] Sent: Tuesday, June 02, 2009 3:13 AM To: MS-Exchange Admin Issues Subject: Outlook Anywhere - Externally I am using Outlook Autodiscover internally with no problems but I haven't had any luck getting Outlook Anywhere working externally.

NTLM is also set as the auth method on the Outlook client. I have ISA and an ASA sitting in front of the CAS but I don't think they are causing the issue. Not sure where else I should be looking?
