What is Microsoft Exchange Server?
Microsoft Exchange or Microsoft Exchange Server is a calendaring and mail server that exclusively runs on Windows Server (such as Windows Server 2003, Windows 2000 Server, etc.) Operating System. It was developed by Microsoft Corp. and was first released on April 11, 1993. Initially, it was an internet mail server from Microsoft. The Exchange Server 4.0 was the very first version of Exchange Server that was published outside Microsoft. It initially used the ITU-T Recommendations suite called X.400, but later shifted to Microsoft’s Active Directory (AD). Newer versions such as 4.0 and 5.0 were bundled with Microsoft Exchange Client; however, it was stopped in favor of MS Outlook.
Exchange Server uses Messaging Application Programming Interface (MAPI), an API-based Component Object Model, which allows the user to send an email inside a Windows application and attach the file to the e-mail note. Subsequently, it also supports POP3 (Post Office Protocol 3), IMAP (Internet Message Access Protocol), SMTP (Simple Mail Transfer Protocol), and EAS (Exchange ActiveSync).

Exchange Server can be acquired through on-premises software or software as a service. The on-premises software means the customer bought a commercial software license called Client Access License (CAL). They can use the service by connecting to server software. Whilst the software as a service means the customer is required to pay a monthly service fee to use the service.
Before Exchange Server, Microsoft had already sold several email-based products, but Exchange Server is a contemporary client-server mail system, which is based on X.400 and also supports the X.500 directory services. Eventually, Exchange Server uses Active Directory (AD), a Microsoft directory service that is acquiescent to LDAP (Lightweight Directory Access Protocol). It is amalgamated into Windows 2000 as the infrastructure of Windows Server domains.
