Daylight Savings Time and Exchange Hybrid Environments -- Remember to apply CU6

Microsoft released June 2017 Quarterly Exchange Update (for Exchange 2016) on June 27, 2017. This pushes the build number to 15.01.1034.026

It's a MUST update for:

• Exchange Hybrid Environments (for more see a recent Sumatra Blog post on hybrid directory structures), particularly when the alias and SAM account names are different.  
• US customers -- it has the latest DST updates.  
• Sumatra's European customers -- it  fixes an error when the mailbox name contains an umlaut (Jörg, Hans-Günther, Köller, Müller, Dück and MANY more will be happy!)
