Question : Unable To Add Outlook Account

I am unable to add a new Outlook account without changing the Logon Network Security Method to Kerberos. I need to find out why the default setting of Negotiate Authentication isn't working. This only is occurring on our 2nd domain that isn't part of the forest that is connected via a VPN tunnel.

Account Settings>More Settings>Security Tab>Logon Network Security

Environment: Exchange 2010, Outlook 2007 SP2, Server 2008 R2
