We have several remote workers who connect to our site through a PPTP VPN which terminates on a firebox. They then connect to out exchange server. however today there is an issue where none of the remote workers are able to use outlook. when the load it it says requesting data from the server.
I am able to ping the server, telnet on the server but not able to connect using outlook. I have deleted the profile and re created it but the name does not resolve. There are no problems internally as everyone else is fine. just externally. Nothing has changed in our system.
also the users are not able to use OWA through the VPN by typing the server IP.
