I have setup a new Exchange server.  I am trying to get Outlook Anywhere to work all the time.  I can connect the first time on a computer and download all the email and it works fine.  If I close Outlook and reopen, it will say trying to connect then Disconneted.  The Outlook Anywhere test is clean and no errors.  I have a wildcard certificate from a public authorithy.  I am baffled how it can work one time only.  If I deleted the user mail and setup from scratch the same thing happens.  Where do I look?  Any thoughts.

I found if I go through a VPN  the connection works.  If I open all my ports on my firewall and leave the firewall on the server up.  The connection works and stays connected. I looked at the connection status and it shows port 6008 and 17337 connected.  I have the https in Outlook configured but it does not seem to be using only the 443 port.

On the Server firewall the The following ports need to be opened. OR You can disable the firewall on the server and open these ports on the router aswell..

SMTP 25 - Simple Mail Transfer Protocol

HTTP 80 - Home Page Web

SSL 443 - Home Page Web Secured HTTPS (RWA, OWA, remote desktop or Terminal Server sessions)

PPTP 1723 - VPN Connections

Note: On SBS 2003, RWW used port 4125. This is now replaced by the Terminal Services Gateway which uses port 443 over HTTPS. The new setup works better for remote locations that have proxy servers which only allow certain types of traffic. HTTPS is so common that it is always an allowed traffic type.
