Powershell Script help request

I have the following script:

#Disabling all ExchangeOnline Services to a specific mailbox
#Aug 2015, Ben Hart @ Unified Brands

Import-Module MSOnline
# Imports the O365 Commandlets

$CloudCredential=Get-Credential -Credential "user@domain.com"
# Saves your User name and password

$CloudSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.outlook.com/powershell/" -Credential $CloudCredential -Authentication Basic -AllowRedirection -WarningAction SilentlyContinue

Import-PSSession $CloudSession -Prefix 365
# Sets the O365 Commands to start with 365

Connect-MsolService -Credential $CloudCredential
# Connects to O365 services

$user = read-host "Enter users email address to disable"

Set-365CasMailbox $user -PopEnabled $False
Set-365CasMailbox $user -ImapEnabled $False
Set-365CasMailbox $user -MapiEnabled $False
Set-365CasMailbox $user -OwaEnabled $False
Set-365CasMailbox $user -ActiveSyncEnabled $False

remove-pssession $CloudSession

Select allOpen in new window

I'd like to change the ending to a get-pssession and if nothing is returned display that there are no sessions that exist.  Like a confirmation that the session was closed successfully.
