Trying to run Connect-ExchangeOnline on an Exchange server 2012 and received the following error message...

It is an Exchange server running Windows Server 2012 Standard with Microsoft Exchange Server 2013 installed.

  • Firewall is not being blocked. Firewall is disabled on the server.
  • I was able to connect to Exchange Online from other machines in the same network (So I know the firewall is not being blocked)

New-ExoPSSession : An error occurred while sending the request..
At C:\Program Files\WindowsPowerShell\Modules\ExchangeOnlineManagement\2.0.3\Ex
changeOnlineManagement.psm1:426 char:30

  • ... PSSession = New-ExoPSSession -ExchangeEnvironmentName $ExchangeEnviro ...
  • ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  • CategoryInfo : NotSpecified: (:) [New-ExoPSSession], Exception
  • FullyQualifiedErrorId : System.Exception,Microsoft.Exchange.Management.E
    xoPowershellSnapin.NewExoPSSession

Thank you,
Stephen

    We have ExchangeOnlineManagement 2.0.3 installed.

    And I tried using ExchangeOnlineManagement 2.0.5, but I still received the same error message.

    Thanks,
    Stephen
