In addition to the new functions, the major changes are: The supported number of mailbox databases has increased from 50 to 100 in the Enterprise Server. Exchange Server 2003 had different storage limits for Standard Server compared with Enterprise Server. In Exchange Server 2007 and Exchange Server 2010, the storage limit is increased to 16 TB for both Standard and Enterprise Server editions. Several high-availability options have been consolidated into just one option for Exchange Server 2010 (Mailbox Resiliency), which is now offered in both the Standard and Enterprise editions. The capabilities of Local Continuous Replication, Standby Continuous Replication, and Cluster Continuous Replication are now unified into the Exchange 2010 Mailbox Resiliency capability. These capabilities enable a simplified approach to high availability and disaster recovery. Prerequisites for Exchange 2010 Server For each Exchange Server 2010 instance, you must also purchase a Windows Server 2008 license. The edition of Windows Server that is required depends on which features of Exchange Server 2010 you will be using. For Exchange 2010 servers that use Mailbox Resiliency features for high availability, either Windows Server 2008 Enterprise or Datacenter editions are required for its clustering features. For all other Exchange 2010 scenarios, Windows Server Standard is appropriate. Therefore, these are the possible scenarios and necessary prerequisites: Exchange Server Edition Scenario Windows Server Edition Exchange Server 2010 Standard Edition No Mailbox Resiliency Standard Server Exchange Server 2010 Enterprise Edition No Mailbox Resiliency Standard Server Exchange Server 2010 Standard Edition Mailbox Resiliency Enterprise /Datacenter Server Exchange Server 2010 Enterprise Edition Mailbox Resiliency Enterprise /Datacenter Server Exchange 2010 Client Access Licenses (CALs) As with the Server licenses, the Exchange Server 2010 CALs have also been significantly improved from the previous versions of Exchange.
