I have a customer that was impacted by hurricane Matthew. He is at the mercy of his local Internet service provider which is currently down. He's running a exchange on a Windows SBS 2011 server. I am looking for a quick solution to enable his office to retrieve the exchange mail coming in until their ISP can get their Internet service back up and running. He has a static IP with his ISP so I'm concerned about being able to set up cellular modem using dynamic IP address is from the cellular company. Not sure that that will work in his case open to suggestions to have to find a resolution quickly!
