I have installed Exchange server 2003 (SP-2) on Windows Server Ent 2003 with SP-2.
Exchange is functioning fine. OWA is working fine with Microsoft CA services (Internally as well as Externally). RPC over HTTP is enabled, but for some reasons are not able to get my account authenticated while configuring remote Outlook clients 2003. Basic authentication has been enabled on RPC virtual Directory.
Remote outlook clients are facing authentication problem while login into Outlook. Outlook is not accepting their user name and password. Outlook clients are configured with Basic authentication.
