If you said (b), do they have VPN connection to your interanet? (a) Yes (b) No If you said (b) they need a VPN connection, or if they are using Outlook 2003 on Windows XP, you need to configure RPC over HTTP. If you said (a) to either question, what procedure have users been given for connecting to the domain? If they don't connect to the Exchange server first, has Outlook been setup to always prompt for password? A machine not in the domain does not automatically work the way a machine in the domain works. You have to put in some extra steps.

Problem: Outlook clients cannot connect to the exchange server if the machine is not part of the domain housing the exchange server. Is there a smart fix for this? Thanks in advance!
