We have several tenants using office 365.  One of these was locked down by an employee who is no longer with the company.   I need to connect to it using PowerShell to make some changes.  

I am using an account which is a global admin and an Exchange admin.  I have tried from my computer and from a computer on the local network and whatever I have tried I get the following error message:

New-PSSession : [] Connecting to remote server failed with the following error message : Access is denied. For more
information, see the about_Remote_Troubleshooting Help topic.
At line:4 char:12
+ $Session = New-PSSession -ConfigurationName Microsoft.Exchange -Conne ...

    + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotingTransportException
    + FullyQualifiedErrorId : AccessDenied,PSSessionOpenFailed
Import-PSSession : Cannot validate argument on parameter 'Session'. The argument is null. Provide a valid value for the argument, and then try running the command again.
At line:5 char:18
+ Import-PSSession $Session -DisableNameChecking

    + CategoryInfo          : InvalidData: (:) [Import-PSSession], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.PowerShell.Commands.ImportPSSessionCommand

Here are the Powershell commands I am using.  They work connecting to other tenants

$orgName="My Company"
$userCredential = Get-Credential -UserName $adminUPN -Message "Type Password"
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session -DisableNameChecking

Any suggestions would be appreciated.
