Editor's Note: Updates added below for important information related to Exchange Server 2010 SP3 Update Rollup 8.

The Exchange team is announcing today a number of releases. Today’s releases include updates for Exchange Server 2013, 2010, and 2007. The following packages are now available on the Microsoft download center.

These releases represent the latest set of fixes available for each of their respective products. The releases include fixes for customer reported issues and minor feature improvements. The cumulative updates and rollup updates for each product version contain important updates for recently introduced Russian time zones, as well as fixes for the security issues identified in MS14-075. Also available for release today are MS14-075 Security Updates for Exchange Server 2013 Service Pack 1 and Exchange Server 2013 Cumulative Update 6.

Exchange Server 2013 Cumulative Update 7 includes updates which make migrating to Exchange Server 2013 easier. These include:

  • Support for Public Folder Hierarchies in Exchange Server 2013 which contain 250,000 public folders
  • Improved support for OAB distribution in large Exchange Server 2013 environments

Customers with Public Folders deployed in an environment where multiple Exchange versions co-exist will want to read Brian Day’s post for additional information.

Cumulative Update 7 includes minor improvements in the area of backup. We encourage all customers who backup their Exchange databases to upgrade to Cumulative Update 7 as soon as possible and complete a full backup once the upgrade has been completed. These improvements remove potential challenges restoring a previously backed up database.

For the latest information and product announcements about Exchange 2013, please read What's New in Exchange 2013, Release Notes and Exchange 2013 documentation on TechNet.

Cumulative Update 7 includes Exchange-related updates to Active Directory schema and configuration. For information on extending schema and configuring Active Directory, please review Prepare Active Directory and Domains in Exchange 2013 documentation.

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., CU7) or the prior (e.g., CU6) Cumulative Update release.

Update 12/12/2014:

Exchange Server 2010 SP3 Update Rollup 8 has been re-released to the Microsoft download center resolving a regression discovered in the initial release. The update RU8 package corrects the issue which impacted users connecting to Exchange from Outlook. The issue was insulated to the MAPI RPC layer and was able to be isolated to quickly deliver the updated RU8 package. The updated RU8 package is version number 14.03.0224.002 if you need to confirm you have the updated package. The updates for Exchange Server 2013 and 2007 were not impacted by this regression and have not been updated.

Update 12/10/2014:

An issue has been identified in the Exchange Server 2010 SP3 Update Rollup 8. The update has been recalled and is no longer available on the download center pending a new RU8 release. Customers should not proceed with deployments of this update until the new RU8 version is made available. Customers who have already started deployment of RU8 should rollback this update.

The issue impacts the ability of Outlook to connect to Exchange, thus we are taking the action to recall the RU8 to resolve this problem. We will deliver a revised RU8 package as soon as the issue can be isolated, corrected, and validated. We will publish further updates to this blog post regarding RU8.

This issue only impacts the Exchange Server 2010 SP3 RU8 update, the other updates remain valid and customers can continue with deployment of these packages.

The Exchange Team
