With the growth of technologies, soft communication and its media have also increased in larger volumes in different formats like e-mail, voice mail, instant message etc… As time progresses, these communication grow bulkier and hence there is a need to eliminate this overload like, specifying rules on how to communicate each other without mixing up the personal life and work, easily communicate with globally distributed customers aside to the development of the business, perhaps to make sure communication cost effective and of course keep it secure against malicious software threats. Exchange server is the one such complete communication system that is designed by Microsoft Corporation.

Microsoft Exchange Server is an enhanced mail server, a contact manager and at the same time calendar software that runs on windows server platforms. The latest known version of this software, as of today, is Exchange server 2013, while Exchange server 2012 and 2010 are its other popular versions. It is a complex messaging platform with components assembled together as a solution for routing, delivering, accessing emails, voice mails, faxes, contacts and calendar information (schedules). Good Exchange administrators, strong architecture and appropriate hardware are thus crucial requirements for Exchange Server set-up. The hardware requirements of the software are: 2 GB minimum RAM (4 GB recommended), x64 family AMD or Intel processors (Intel Xeon 3.4 Ghz or AMD Opteron 3.1 GHz and higher recommended) with cache and added advantage with RAID configuration.

The services included in an exchange server (updates until Exchange server 2010 are considered) are not concluded in providing basic FTP and mail services like SMTP, POP, IMAP services etc… The definitions in Exchange services includes: introducing active directory topology to Exchange services, managing an address book connections, maintaining an anti-spam data (Forefront Security), providing Edge sync and file distribution services between email server replicas, indexing of mailboxes for better search techniques, supporting client RPC connections, tracing and fixing throttling issues within the system, setting up speech recognition services, including an overall monitoring, maintenance as well as look up services. Forefront Security software is one of the important part of the Exchange server. It is the main security component and its functions are: anti-spam update, Exchange Web Services (EWS) or Exchange ActiveX Directory Objects (ADO) navigation, security controller for the communication of Exchange servers and eventing services managing logs.

Email Archiving, protection of data and communication with a vivid set of tools and advanced security mechanisms enforce Protection and Compliance. The Anywhere Access policy of Exchange servers is achieved by maintaining different replicas and failover mechanisms. It keeps load management systems in software level as well as in network level. It also maintains a simple administration interface and ensures ease of access. The different levels in this software make it to deploy as per the need of the organization. All this makes the system Flexible, Economical and Reliable.

Exchange servers thus attract the corporate world with its unique advantages in the field of communication.
