Exchange Server also introduced active-active clustering, but for two-node clusters only. In this setup, both servers in the cluster are allowed to be active simultaneously.
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. They must wait, inactive, for the home servers in the node to fail. Subsequent performance issues with active-active mode have led Microsoft to recommend that it should no longer be used.
Exchange'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. The clustering in Exchange Server provides redundancy for Exchange Server as an application, but not for Exchange data.
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. The limitation of CCR clusters is the ability to have only two nodes and the third node known as "voter node" or file share witness that prevents "split brain"  scenarios, generally hosted as a file share on a Hub Transport Server. The second type of cluster is the traditional clustering that was available in previous versions, and is now being referred to as SCC Single Copy Cluster.
It is designed to allow for data replication to an alternative drive attached to the same system and is intended to provide protection against local storage failures. It does not protect against the case where the server itself fails.
Unlike CCR, which requires that both servers belong to a Windows cluster typically residing in the same datacenter, SCR can replicate data to a non-clustered server, located in a separate datacenter.
When a Mailbox server is added to a DAG, the Failover Clustering Windows role is installed on the server and all required clustering resources are created. It also comes as part of the Core CAL. User and Device CALs have the same price, however, they cannot be used interchangeably.

Standard and Enterprise. They differ in database store size, mail transport connectors, and clustering capabilities. Adds an X. Introduced two node clustering capability. Exchange Server [ edit ] Codenamed "Platinum", this version overcame many of the limitations of its predecessors.
For example, it raised the maximum sizes of databases and increased the number of servers in a cluster from two to four. However, many customers were deterred from upgrading by the requirement for a full Microsoft Active Directory infrastructure to be in place, as unlike Exchange Server 5. The migration process from Exchange Server 5. Exchange Server also added support for instant messaging , but that capability was later spun off to Microsoft Office Live Communications Server.
Exchange Server [ edit ] Codenamed "Titanium", this version can be run on Windows Server with Service Pack 4 and bit Windows Server , although some new features only work with the latter. Like Windows Server , Exchange Server has many compatibility modes to allow users to slowly migrate to the new system. This is useful in large companies with distributed Exchange Server environments who cannot afford the downtime and expense that comes with a complete migration.
It made the migration from pre versions of Exchange significantly easier although still involved the same basic steps , and many users of Exchange Server 5. The upgrade process also required upgrading a company's servers to Windows Some customers opted to stay on a combination of Exchange Server 5. One of the new features in Exchange Server is enhanced disaster recovery,  which allows administrators to bring the server online more quickly.
This is done by allowing the server to send and receive mail while the message stores are being recovered from backup. Also new is the ability to drop inbound e-mail before being fully processed, thus preventing delays in the message routing system. There are also improved message and mailbox management tools, which allow administrators to execute common chores more quickly. Others, such as Instant Messaging and Exchange Conferencing Server have been extracted completely in order to form separate products.
Exchange Server is now to be simply e-mail and calendaring. Exchange Server added several basic filtering methods to Exchange Server. They are not sophisticated enough to eliminate spam, but they can protect against DoS and mailbox flooding attacks.
New features[ edit ] Added filtering methods in Exchange Server are: Connection filtering: Messages blocked when sent to manually specified recipients on the server for intranet-only addresses or to any recipients not on the server stopping spammers from guessing addresses Sender ID filtering: Initially a free Microsoft add-on, later, part of service pack 2, that uses heuristic message analysis to block messages or direct them to the "Junk E-Mail" folder in Microsoft Outlook clients.
Editions[ edit ] Standard Edition: Supports up to two storage groups with one of the storage groups, called the recovery storage group, being reserved for database recovery operations and a maximum of two databases per storage group. Exchange mainstream support ended on April 14, It includes new clustering options, x64 support for greater scalability, voice mail integration, better search and support for Web services, better filtering options, and a new Outlook Web Access interface.
Exchange also dropped support for Exchange 5. This requirement applies to supported production environments only; a bit trial version is available for download and testing. Hence, companies currently running Exchange Server on bit hardware will be required to replace or migrate hardware if they wish to upgrade to the new version. The first beta of Exchange Server then named "Exchange 12" or E12 was released in December to a very limited number of beta testers.
Exchange Server is an integrated part of the Innovative Communications Alliance products. Anti-spam, antivirus, compliance, clustering with data replication, improved security and encryption Improved Information Worker Access: Improved calendaring, unified messaging, improved mobility, improved web access Improved IT Experience: Shell users can perform every task that can be performed in the Exchange Server graphical user interface plus additional tasks, and can program often-used or complex tasks into scripts that can be saved, shared, and re-used.
Lets users receive voice mail, e-mail, and faxes in their mailboxes, and lets them access their mailboxes from cell phones and other wireless devices.
