Is the IMAP service set to Automatic and started? By default in Exchange 2003 and above, it is not. And does your firewall have the port open? And in Exchange 2007, unless you specifically enable plain text passwords, you'll need to install an SSL certificate as well.

We are testing using Outlook Express and get the following message: I just tried an got the following error: "No connection could be made because the target machine actively refused it." My first thought is that the IP address is not being allowed to talk to the Exchange server, but checking access permissions the IP's of the clients are allowed - we're trying to connect from the same LAN as the Exchange box. Where should I look next?
