Currently our email is hosted by a web hosting company and is pop3. I would like to install microsoft exchange on our local server. We have windows server 2008 R2 installed and we already use active directory etc.
The only problem is that we get the odd power cut. The nature of our business means that we cannot afford to miss emails. If the power goes out and our server goes offline, what happens when people are trying to send us emails, do they get stored on another server somewhere? Or do we need a additional backup server somewhere else that comes online when ours is offline?
