I'm currently using Exchange Server 2003 and ESoft Instagate 604 as my firewall and spam filter for the organization. I set up a single site connector that has the Exchange server as the bridgehead, and I point the connector to the IP address of the Instagate box. This works fine but I have three users that use the Blackberry Desktop re-connector and they continue to receive error messages in their Outlook inboxes indicating that Blackberry can't send to that user. Can anyone help correct these errors?
Software/Hardware used: Exchange Server 2003, Blackberry mobile device, Outlook
