Exchange Server 2013 Cumulative Update 5
The Exchange team has announced Cumulative Update 5 for Exchange Server 2013 and updated UM Language Packs are now available on the Microsoft Download Center.
Cumulative Update 5 represents the continuation of our Exchange Server 2013 servicing and builds upon Exchange Server 2013 Service Pack 1. The release includes fixes for customer reported issues, minor product enhancements and previously released security bulletins.
A complete list of customer reported issues resolved in Exchange Server 2013 Cumulative Update 5 can be found in Knowledge Base Article KB2936880.
Customers running any previous release of Exchange Server 2013 can move directly to Cumulative Update 5.
Customers deploying Exchange Server 2013 for the first time may skip previous releases and start their deployment with Cumulative Update 5 as well.
Cumulative Update 5 includes Exchange related updates to Active Directory schema and configuration. For information on extending schema and configuring the active directory please review the appropriate TechNet documentation. Also, to prevent installation issues you should ensure that the Windows PowerShell Script Execution Policy is set to “Unrestricted” on the server being upgraded or installed. To verify the policy settings, run the Get-ExecutionPolicy cmdlet from PowerShell on the machine being upgraded. If the policies are NOT set to Unrestricted you should use the resolution steps in KB981474 to adjust the settings.
Reminder: Customers in hybrid deployments where Exchange is deployed in-house and in the cloud, or who are using Exchange Online Archiving with their in-house Exchange deployment are required to maintain currency on Cumulative Update releases.
