This type of cluster can be inexpensive and deployed in one, or "stretched" across two data centers for protection against site-wide failures such as natural disasters. Įxchange Server 2007 provides built-in support for asynchronous replication modeled on SQL Server's " Log shipping" in CCR (Cluster Continuous Replication) clusters, which are built on MSCS MNS (Microsoft Cluster Service-Majority Node Set) clusters, which do not require shared storage. Exchange Server 2007 introduces new cluster terminology and configurations that address the shortcomings of the previous "shared data model". This void has however been filled by ISVs and storage manufacturers, through "site resilience" solutions, such as geo-clustering and asynchronous data replication. In this scenario, the data can be regarded as a single point of failure, despite Microsoft's description of this set-up as a "Shared Nothing" model. The clustering in Exchange Server provides redundancy for Exchange Server as an application, but not for Exchange data. In fact, support for active-active mode clustering has been discontinued with Exchange Server 2007.Įxchange's clustering (active-active or active-passive mode) has been criticized because of its requirement for servers in the cluster nodes to share the same data. Subsequent performance issues with active-active mode have led Microsoft to recommend that it should no longer be used.

They must wait, inactive, for the home servers in the node to fail. This is opposed to Exchange's more common active-passive mode in which the failover servers in any cluster node cannot be used at all while their corresponding home servers are active.

In this setup, both servers in the cluster are allowed to be active simultaneously. Exchange Server 2003 also introduced active-active clustering, but for two-node clusters only.

Unified Messaging continues to exist in Exchange Online requiring an Exchange Plan 2 license. 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. One of the key features of the new release is that Exchange Server can be deployed onto Windows Server Core for the first time. Unlike other Office Server 2019 products such as SharePoint and Skype for Business, Exchange Server 2019 can only be deployed on Windows Server 2019. The current version, Exchange Server 2019, was released in October 2018. The directory used by Exchange Server eventually became Microsoft's Active Directory service, an LDAP-compliant directory service which was integrated into Windows 2000 as the foundation of Windows Server domains.Īs of 2020, there have been ten releases. Microsoft had sold a number of simpler email products before, but the first release of Exchange (Exchange Server 4.0 in March 1996) was an entirely new X.400-based client–server groupware system with a single database store, which also supported X.500 directory services.

The standard SMTP protocol is used to communicate to other Internet mail servers.Įxchange Server is licensed both as on-premises software and software as a service (SaaS). This was discontinued in favor of Microsoft Outlook.Įxchange Server primarily uses a proprietary protocol called MAPI to talk to email clients, but subsequently added support for POP3, IMAP, and EAS. Until version 5.0 it came bundled with an email client called Microsoft Exchange Client. Exchange initially used the X.400 directory service but switched to Active Directory later. The first version was called Exchange Server 4.0, to position it as the successor to the related Microsoft Mail 3.5. It runs exclusively on Windows Server operating systems. Microsoft Exchange Server is a mail server and calendaring server developed by Microsoft.
