Download the file here:
The above document is a couple years old. You can find updated information in this article from Microsoft.

In the details pane, right-click the ValidPorts subkey, and then click Modify.
In Edit String, in the Value data box, type the following information:

ExchangeServerFQDN is the fully qualified domain name (FQDN) of your Exchange server. If the FQDN that is used to access the server from the Internet differs from the internal FQDN, you must use the internal FQDN.
