My employer is wanting to install Exchange 2003. This will be a initial setup, all of our e-mail is being handled through an outside provider right now. Does anyone have the abc's or a reference for an initial Exchange 2003. Everything I read makes it sound fairly complicated. I am sure when we do this it will be a weekend and management will expect it to be up and running by the following Monday. Is that realistic? Or can we expect e-mail service to be down for a while? Any help would be appreciated.
