I have a member of staff that accesses his mail from our SBS server via pop3 from his laptop. When he comes into the office his outlook cannot connect to the server.
I have set up a forward lookup DNS record and when he is in the office, pinging mail.ourdomain.com from his laptop does resolve to the exchange server 192.168.1.x
I cannot understand why exchange will not allow the connection when the request comes from the local network. Any help would be great!
