Communication is very important in the business world--especially when it comes to business email. Gone are the days when communication was solely done through paper and pencil and then delivered through snail mail. Electronic messaging is now a very important part of businesses. Due to the volume of business trades around the world, a faster and more efficient system that would handle exchange of messages and manage communication between servers is a necessity. Business email needs to travel quickly and efficiently to its recipient. This is where exchange servers come into play. You may be wondering, "How does an exchange server work?" Let's discuss more about them. Here's how to understand them.

An Exchange Server is an application intended to handle a corporate messaging system. The email server system supports both internal and external electronic messages. The Exchange Server processes the messages into four basic steps.

  1. First, the client who will be sending a message shall connect to the exchange servers and then send the message.
  2. The server then processes the message by storing it in the appropriate location in the messaging database.
  3. After which, the server informs the recipient of the message's arrival.
  4. The recipient of the message then connects to the server to retrieve the message.

To process the messages, the Exchange Server has four core components that make exchanges of communication happen. These four core components assist to organize, distribute and receive messages from other processes and operations.

  1. Information Store
  2. System Attendant
  3. Simple Mail Transfer Protocol (SMTP)
  4. Active Directory Service.

The Information Store Service takes charge in managing the Information Store. The other system of this component is the Extensible Storage Engine (ESE), which manages the internal structure of the database file. The ESE is responsible for processing the requests from the first processes, then writes the message data into the file.

Messages to be delivered between and among servers are routed and processed by the Simple Mail Transfer Protocol. The Active Directory Service is managed by the domain controller. To manage user's mailboxes, distribution lists and server properties, Exchange 2000 and 2003 use the Active Directory service.

Users can receive and send email from their local email client through the email address assigned to them by their company. The Exchange Server also provides protection from viruses and spams that infiltrators would use in trying to damage the company's system. Through the Exchange Server, employee contact lists can be created and easily accessed. Schedules, whether personal or for teams in the department, can be made and managed through shared calendars. The shared tasks help team members or employees manage their projects and activities. Through this function, each member gets involved in group activities, since they can maintain to-do lists of assigned tasks and even personal tasks. Company information is easily accessible through the shared folders.

Storage and distribution of company information is centralized through this function. The latest function of Exchange Server is Outlook Web Access. This function provides more flexibility to its users, since this allows them to access their Outlook account from the Internet and from their mobile devices.

Now you can answer you question, "How does an exchange server work?" The basic functions of an Exchange Server are business email, protection, shared contacts, shared calendar, shared tasks, shared folders, outlook mobile and web access, and outlook web access.
