==History==
{{Main article| History of Microsoft Exchange Server}}
Microsoft had sold a number of simpler email products before, but the first release of Exchange (Exchange Server 4.0 in April 1996<ref name="initial-release">{{Cite web |date=2 April 1996 |title=Microsoft Exchange Server Available |url=https://news.microsoft.com/1996/04/02/microsoft-exchange-server-available/ |access-date=5 Feb 2023 |website=[[Microsoft]]}}</ref>) was an entirely new [[X.400]]-based [[client–server]] groupware system with a single database store, which also supported [[X.500]] directory services. The directory used by Exchange Server eventually became Microsoft's [[Active Directory]] service, an [[Lightweight Directory Access Protocol|LDAP]]-compliant directory service which was integrated into [[Windows 2000]] as the foundation of [[Windows Server domain]]s.

As of 2020, there have been ten releases.
 
===Current version===
The current version, Exchange Server 2019,<ref>{{Cite web|url=https://www.frankysweb.de/microsoft-kuendigt-exchange-2019-an/|title = Microsoft kündigt Exchange 2019 an|date = September 26, 2017}}</ref> was released in October 2018. Unlike other Office Server 2019 products such as SharePoint and Skype for Business, Exchange Server 2019 could only be deployed on Windows Server 2019 when it was released. Since Cumulative Update 2022 H1 Exchange 2019 has been supported on Windows Server 2022.<ref>{{Cite web |date=2022-04-20 |title=Released: 2022 H1 Cumulative Updates for Exchange Server |url=https://techcommunity.microsoft.com/t5/exchange-team-blog/released-2022-h1-cumulative-updates-for-exchange-server/ba-p/3285026 |access-date=2022-04-21 |website=TECHCOMMUNITY.MICROSOFT.COM |language=en}}</ref> One of the key features of the new release is that Exchange Server can be deployed onto Windows Server Core for the first time. Additionally, Microsoft has retired the Unified Messaging feature of Exchange, meaning that Skype for Business on-premises customers will have to use alternative solutions for voicemail, such as Azure cloud voicemail.
