The Cumulative Update 10 for Microsoft Exchange Server 2013 and the Exchange Server 2010 Service Pack 3 Update Rollup 11 has just been released. Both releases includes a range of fixes for customer reported issues, minor product enhancements and previously released security bulletins.
Cumulative Update 10 for Exchange Server 2013
The CU10 package contains the full Exchange server binaries and can both be used for installing a new installation of Exchange 2013, as well as upgrading an existing Exchange Server 2013 installation.
Note that Cumulative Update 10 does not include updates to Active Directory Schema, but does include new RBAC definitions, which require PrepareAD to be executed before to upgrading any Exchange Server to CU10. During the first server upgrade or installation, PrepareAD will automatic run if the Setup wizard determines it is required, and the logged on user has sufficient permission to perform the change.
To avoid issues during installation or upgrade, ensure the Windows PowerShell Script Execution Policy is set to “Unrestricted” on the server used for performing the upgraded or installation.
For Hybrid deployments, where Exchange is deployed on-premises, or in the cloud, or when Exchange Online Archiving (EOA) is used with the on-premises Exchange deployment, must deploy the most current (currently CU10) or the prior (currently CU9) Cumulative Update release.
Exchange Server 2010 Service Pack 3 Update Rollup 11
Ensure to get this new update for Exchange Server 2010 SP3 installed, before beginning upgrading the Lync server infrastructure to Skype for Business, as this update included an important fix for an Information Store crash during the Lync upgrade.
Preparing for Exchange Server 2016
Support for co-existence with Exchange Server 2016, which is expected to be released later this year, will require a minimum of Cumulative Update 10 for Exchange Server 2013 and Update Rollup 11 for Exchange Server 2010 Service Pack 3.
