Experience and Telemetry requests to a proxy server.

If you enable this policy setting, you can specify the FQDN or IP address of the destination device
within your organization's network (and optionally a port number, if desired). The connection will
be made over a Secure Sockets Layer (SSL) connection.

If the named proxy fails, or if you disable or do not configure this policy setting, Connected User
Experience and Telemetry data will be sent to Microsoft using the default proxy configuration.

The format for this setting is <server>:<port>
