Microsoft released Quarterly release for the September month-2016, Below are the important updates for Exchange.
Note: This release majorly supports for Exchange 2013 and 2016. There is no Updates for Exchange 2010 in the release. Which clearly indicates that Microsoft significantly reduced investing for further developments and there will be a plan to deprecate the version very soon.
Windows Server 2016 Support
Windows Server 2016 support is now available with Exchange Server 2016 Cumulative Update 3
Exchange Server 2013 will not be supported on Windows Server 2016.
Windows Defender is on by default in Windows Server 2016. Attention to malware settings is particularly important with Exchange to avoid long processing times during installation and upgrade, as well as unexpected performance issues. The Exchange team recommends the Exchange installation and setup log folders be excluded from scanning in Windows Defender and other Anti-Virus software. Exchange noderunner processes should also be excluded from Windows Defender.
.Net 4.6.2 Support
Net 4.6.2 is included with Windows Server 2016. Customers deploying Exchange on Windows Server 2016 must use
Microsoft planed to add support for .Net 4.6.2 on Windows Server 2012 or Windows Server 2012R2 in our December releases of Exchange Server 2016 and 2013. .Net 4.6.2 will be required for Exchange Server 2016 and 2013 on all supported operating systems in March 2017
High Availability Improvements
The local search instance reads data from a database copy on the local server, also known as “Read from Passive”. As a result of this change, passive HA copy search instances no longer need to coordinate with their active counterparts in order to perform index updates. Lagged database copies still coordinate with their active counterparts to perform index updates. This change also reduces database failover times when compared to Exchange Server 2013.
Pre-Requisite Installation Behavior Updated
In previous releases of Exchange Server 2016 and 2013, servers were placed into server-wide off-line monitoring states during pre-requisite analysis and pre-requisite installation. This behavior is changed in the September cumulative update releases. Setup will now place a server in off-line monitoring mode when installation of new Exchange binaries begins. This change allows customers who are using the GUI upgrade experience to delay changing the monitoring state until after pre-requisite analysis confirms the server is ready for installation.
Refreshed People Experience in Outlook on the web
Exchange Server 2016 Cumulative Update 3 includes an updated view of Contact information and Skype for Business presence information. These changes mirror the current experience of Office365.
Countdown to Exchange Server 2007 End of Life (EOL)
now only seven months away from Exchange Server 2007 going out of support (Exchange Server 2007 T-1 year and counting).
