Add a Prefix to Differentiate On-Prem from Cloud Exchange Cmdlets

If you use PowerShell to manage both on-prem and cloud Exchange resources, you can manage both¬†in the same¬†console by adding a prefix to the cmdlets of one or the other. It’s easier to add the prefix for Exchange Online cmdlets, so I’ll show you that.

Simply copy and paste this code into the on-prem Exchange Management Shell to connect to Exchange Online and prefix the noun portion of all online cmdlets with “Cloud”. The verb portion of the cmdlets doesn’t change, so Get-Mailbox becomes Get-CloudMailbox, and Get-AcceptedDomains becomes Get-CloudAcceptedDomains.

$Cred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange `
     -ConnectionUri `
     -Credential $Cred -Authentication Basic -AllowRedirection
Import-PSSession $Session -Prefix Cloud

Here’s how it looks in the shell:
