June 2016 Updates for Exchange Server 2016/2013

Microsoft has released the latest cumulative updates for Exchange Server 2016 and 2013 this month, with the release of:

  • Exchange Server 2016 Cumulative Update 2 (download)
  • Exchange Server 2013 Cumulative Update 13 (download)

You might also like to know that Exchange 2010 and 2007 received updates earlier in the month.

The new CUs for Exchange 2016 and 2013 deliver some significant changes:

  • Exchange 2016 CU2 includes new behavior for automatic rebalancing of database availability groups
  • .NET Framework 4.6.1 is now supported, only for Exchange 2016 CU2 and Exchange 2013 CU13. There are specific steps required to safely upgrade .NET Framework to 4.6.1.
  • AutoReseed now supports BitLocker. Few customers I know have bothered to BitLocker encrypt their disks, but for those that do, and who also rely on AutoReseed, this will be welcome news.
  • New-ExchangeCertificate will now produces SHA-2 certificates for all self-signed certificates. This only impacts automatic generation of new certificates, not renewals of existing certificates. However, you can replace your SHA-1 certificates manually after you’ve upgraded to Exchange 2016 CU2 or Exchange 2013 CU13.
  • Get-ExchangeServer now returns ServerRole attributes consistent with the new server roles architecture in Exchange 2016. This is most likely to impact custom scripts that rely on the ServerRole attribute to identify server functionality.
  • The issue that could cause data loss for public folder migrations has been fixed.

    Paul,

    First – I want to say thank you for all your articles. I can’t tell you how many times I have googled various things about Exchange and I always seem to end my search with your posts because of the breadth of knowledge and presentation of the material. I completely understand what I’m doing and how to accomplish it after reading your stuff.

    Second – The download link for 2016 CU2 seems to be broken.

    Thanks,
    Larry McFarlin
