The first of these is what most call a Local Area Network Administrator. This is a technology professional dedicated to operating the in-house network and troubleshooting the day-to-day computer issues that arise from the cubicle to the board room. A significant percentage of this person's time will be spent dealing with email-related issues.
Directory administration is a clerical, non-technical position, but it is intimately tied to the in-house technology issue. These individuals keep a thorough database of user moves and changes, new passwords and usernames, or the expiration of the same. This is a position that would become redundant in the case of outsourcing.
An even more costly position to fill is that of the email server specialist. This is a technical professional who may have little to no direct contact with employees, but without whose services the email system would probably cease to work in a matter of days. This position probably also acts as a liaison with the software or hardware vendors—a relationship that is indispensable.
Any number of additional staff will be required in various support roles if you chose to operate an in-house email system. Administrative, clerical, and technical, all work together to provide a seamless user experience for the other employees. If even one is removed, the chain of user support is weakened or broken, and even more oppressive financial strains will be placed on the company.
