With the Mac Beta I can install Outlook 2000, create a profile and run the 'Check Name' command against the exchange server, it connects successfully and replaces the UID with my account display name (full name) but when I try to start the main outlook executable it hangs at the splash screen after re-requesting the username/domain name/password.
I've tried fixing the /etc/hosts file, and changing my MS Domain security policy to allow NTLMv1 authentication.
