The odd thing is that when I set it to NTLM on Outlook 2003 it doesn't work (I get prompted). Outlook 2002 doesn't have Kerberos so the NTLM prompts me too.
It should use NTLM also right?
Thanks

Question
Exchange 2003 Authentication
I'm using exchange 2003 and I can access a mailbox fine using Outlook 2003. The authentication on Outlook 2003 is set for Kerberos/NTLM Password authentication.
If I try with a Outlook 2000 or Outlook 2002 client I am prompted for a username and password and I can't authenticate or access the mailbox.
I know the Kerberos authentication setting is the key. That can't be set on Outlook 2000 from the advanced tab.
Is there anyway to set Exchange 2003 to use NTLM and Kerberos?
Thanks
Mike

Out of the box that is what is suppose to occur, it attempts Kerberos authentication and then roles back to Ntlm.
