Finally got Exchange 2003 configured to use RPC over HTTPS so clients do not have to VPN in. I have outlook 2003, WinXP SP2, and have set it up such that I can access my exchange mailbox using RPC over HTTPs. Everything's working fine--however there is one slightly annoying issue. Every time I start Outlook, I am confronted with the domain login box, prepopulated with the DOMAIN\USERNAME in which I have to enter in my password. Can this be made to go away? There is no option to save my password (at least not in this domain prompt).
The email account settings box under user authentication "always prompt for username and password" is unchecked.
