Firstly, I am no Exchange expert. I have just joined a company after the senior IT guy suddenly left for personal reasons. Unfortunately, he was THE main exchange person. To my (untrained) eye, the exchange set up is somewhat lacking. Exchange 2k is installed on a single server, no clustering, no resilience whatsover and is a major possible point of failure for a company that conducts most of its business via email. I havent been asked to improve the situation, but feel that I would be failing if I didnt at least present them with the possible disaster scenario and a resolution for it. Any suggestions on what would be the best way forward would be much appreciated.
