Exchange 2016 cmdlet help

help is broken in Exchange 2016 PowerShell console - the only way to make it work i found to be this:

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://exchangeservername/PowerShell/?SerializationLevel=None

Invoke-Command –Session $Session –ScriptBlock {Get-Help Get-Mailbox}

but you will not be abble to import the exchange cmdles through this pssession because it will throw an error.

to import the cmdlest you need to have a different pssession without "SerializationLevel=None"

$Session2 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://exton.office.orange.intra/PowerShell

Import-PSSession $Session2
