Ok. 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. And as previously mentioned ISA is sitting in front of those for external access. Hope that helps! From: Joseph L.

I sort of recently tore my hair out over this so I may have some ideas.

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?
