UPDATED: Exchange 2013 RTM CU2
The previously released Exchange Server 2013 RTM Cumulative Update 2 (CU2) has now been updated to version 15.00.0712.024 and is available to download.
This new version corrects an issue with Public Folders, as described in this blog post.
If you have not deployed Exchange 2013 RTM CU2, you can follow the steps outlined in the Upgrading/Deploying Cumulative Update 2 section in the Exchange 2013 RTM CU2 announcement article.
If you have already installed Exchange 2013 RTM CU2 (712.22), you can simply execute setup.exe /m:upgrade /IAcceptExchangeServerLicenseTerms from a command line to upgrade your servers to the 712.24 build; alternatively you can upgrade via the setup user interface. Attempting to uninstall the 712.22 build will result in the complete uninstall of the server and is not recommended.
Important: Regardless of whether you are using modern public folders, we strongly recommend upgrading to this build of Exchange 2013 RTM CU2. Any security updates released for CU2 will be dependent on this build.
