If your organization is anything less than gargantuan, having an in-house email connectivity department can be impossible. You might not have enough volume to warrant a full department of specialists to keep at your beck and call. What often happens, then, is that organizations rely on a single individual to keep systems up and running. Consider, for example, how often you depend upon the storied “IT Guy.” While it’s definitely smart to have someone on your staff who is well versed in computers and networks, you might not want to have your entire email operation ensconced in the knowledge of just one individual. If you were for some reason to lose that individual suddenly, would someone else be able to step right in? Probably not. Most systems rely as much on anecdotal on-the-job knowledge as book-learning—meaning that single individual is incredibly important to keeping things up and running. In the case of a sophisticated email system, it might be wise to keep functions outsourced to an external organization where there are many specialists ready to step in and take over should the need arise.
