, HI,

yesterday, after installing the latest CU 2016 update CU23 Nov23SU 15.1.2507.35, we encountered some strange behavior with some Exchange Powershell commands:

for example: Get-ExchangeServer | Test-MAPIConnectivity

but if I run a single command, Get-ExchangeServer and Test-MAPIConnectivity, not in pipes, it works.

Furthermore, the script to move db between nodes, stops to work:

.\RedistributeActiveDatabases.ps1 -DagName "DAG" -BalanceDbsByActivationPreference -SkipMoveSuppressionCh
ecks
Cannot convert value "DAG" to type "Microsoft.Exchange.Data.Directory.SystemConfiguration.DatabaseAvailabilityGroup". Error: "Cannot convert the "DAG"

    Hi @Claudio Di Chiaro ,

    Did you run the command or scripts on Management Tools only machines? If so, it appears that both the two issues have already been aware of, and fixes are currently being working on. For more information and the possible workaround for now, you can refer to the official links below:
