As usual first try to install the CU and Update Roll-up in your Lab environment and perform thorough testing to validate the Issues Fixed as stated under each update and also look out for any new issues you might experience to report to Microsoft on time and get it fixed before you roll out these updates to your Production Environment.


Unfortunately Exchange Server 2013 CU6 couldn't keep itself up to the standard as its predecessor CU5, It caused two major issues within few days post its release identified by our renowned MVPs. Microsoft acknowledged and confirmed that these are bugs from their end which caused a huge disappointment to the Exchange Community. Still Microsoft needs more testing and bug fixing on their end before releasing any updates to avoid unexpected issues.
