The Exchange team is announcing today the availability of our latest quarterly updates for Exchange Server 2013 as well as updates for Exchange Server 2010 Service Pack 3 and Exchange Server 2007 Service Pack 3.
Cumulative Update 9 for Exchange Server 2013 and UM Language Packs are now available on the Microsoft Download Center. Cumulative Update 9 contains the latest set of fixes and builds upon Exchange Server 2013 Cumulative Update 8. The release includes fixes for customer reported issues, minor product enhancements and previously released security bulletins. A complete list of customer reported issues resolved can be found in Knowledge Base Article KB3049849. Customers running any previous release of Exchange Server 2013 can move directly to Cumulative Update 9 today. Customers deploying Exchange Server 2013 for the first time may skip previous releases and start their deployment with Cumulative Update 9 directly.
Cumulative Update 9 may include Exchange related updates to the Active Directory schema and Exchange configuration when compared with the version of Exchange 2013 you have currently deployed. Microsoft recommends all customers test the deployment of a cumulative update in their lab environment to determine the proper installation process for your production environment. For information on extending the schema and configuring 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 on-premises and in the cloud, or who are using Exchange Online Archiving (EOA) with their on-premises Exchange deployment are required to deploy the most current (e.g., CU9) or the prior (e.g., CU8) Cumulative Update release.
Also being released today are, Exchange Server 2010 Service Pack 3 Update Rollup 10 (KB3049853) and Exchange Server 2007 Service Pack 3 Update Rollup 17 (KB3056710). These releases provide minor improvements and fixes for customer reported issues. Update Rollup 10 is the last scheduled release for Exchange Server 2010. Both Exchange Server 2010 and Exchange Server 2007 are in extended support and will receive security and time zone fixes on-demand on a go-forward basis.
