I have 2 servers in a domain - a Windows 2000 server (SP4) running as a AD Domain Controller/File and Print server, and a Windows 2000 server (SP4) running ISA server 2000 (SP1). I have just recently installed Exchange 2003 on the ISA server (running in native mode). There was 10 pre-existing domain accounts prior to the exchange install, and I have created one new account since the exchange install. All pre-existing accounts had personal folders set up in outlook 2003.
When I try to add the Exchange service to any existing user (running Outlook 2003) I can resolve the user's mailbox on the Exchange server, as long as I don't change the data store to the Exchange mailbox (ie leave as Personal Folders). If I try to change this, I get the following message "The specified default store could not be opened. Please make sure you can access your default store and try again". If I try to resolve the exchange properties of the newly created user, I get an error message saying outlook is offline.
Please advise if you require any further information.
Thanks in advance.
