One of my customers has been down due to a failure from their ISP. They are trying to use one of the Mobile Internet USB sticks to try and limp along until the ISP can get their service restored.
I am very much a newbe when it comes to Exchange 2007. We have disabled the MX record from their website. Where would I go in Exchange 2007 to set a specific SMTP route to see if we could send emails through this USB Mobile Internet unit?
