It was a big month for Exchange updates. Not only did we get Cumulative Update 15 for Exchange 2013, but we also got Cumulative Update 4 for Exchange 2016.
As always, test these updates in a lab first! I recommend checking out this 7-part guide on configuring Exchange in your lab. It doesn’t take much to get one going.
The updates are as follows:
A quick word on Exchange 2007
It’s time to update. Exchange 2007 will go end of life on April 11th, 2017. That’s a little over 4 months. If you are counting the days from this blog post that is exactly 100 days before Microsoft drops all support for Exchange 2007. On April 12th you will receive no more patches and no more telephone support.
If the lack of security updates from Microsoft isn’t convincing enough, check this article for a list of cool things Exchange 2013 can do. (P.S. Like the fact Exchange 2013 uses fewer IOPS per mailbox than 2007…say what?)
Windows Server 2016 was breaking Exchange 2016
Cumulative Update 3 for Exchange 2016 officially added support for deployment on Windows Server 2016. Unfortunately, it was quickly realized that a bug existed that would crash the IIS Application Pools after a reboot of a freshly installed DAG member. The Server Team’s official response can be found here.
It is worth noting that Exchange 2016 CU4 will not install on Windows Server 2016 unless this update is present. [Read more…] about Exchange December 2016 Updates
