Re: ActiveSync via USB to Exchange server failing locally, not remote

Hi,
In the office, do you use a Proxy Server? If so then the SDA may not
connect unless the proxy server is configured to allow it to connect (the IP
address). Also, you may have to configure the proxy server on the device.
This may cause problems when you are away from the office because the proxy
is not available.
