Microsoft released the latest round of updates today. As always, many updates were included and this round included security update for MS14-075, which can be downloaded for 2013 SP1/CU5 & 2013 CU6 if you just want to apply this security update and not 2013 CU7 now. This latest round was delayed due to some issues found with the install process, see Tony Redmond’s post on this here and a short post on the EHLO blog here for more info.

Microsoft Exchange Team EHLO Blog Post: Exchange releases: December 2014

Key updates:

• 2013: Support for Public Folder Hierarchies with up to 250,000 folders
• 2013: Improved OAB distribution in larger environments
• 2013: Important updates to backup
• 2013: AD Schema update
• 2013: Updates to backup code

If your organization is still using Public Folder and coexisting with Exchange 2007 or 2010 make sure you read this EHLO Blog post: On-Premises Legacy Public Folder Coexistence for Exchange 2013 Cumulative Update 7 and Beyond

There were some changes with the backup code\API in the 2013 CU7 update, therefore it is highly recommended that you do a full backup after installing CU7. In addition, you should test your backup AND recovery procedures and programs to ensure they are still working as expected after applying CU7. The changes affect the ESE database engine that can cause restores to fail.

Note: For those organizations running Exchange in a Hybrid configuration with Exchange Online (EXO)/Office 365 or using Exchange Online Archiving (EOA) you are required to deploy the most current updates.
