(Get-HybridMailflowDatacenterIPs is not recognized) error when running Hybrid Configuration wizard
Original KB number: 3063646
The Hybrid Configuration wizard that's included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration wizard. Instead, use the Office 365 Hybrid Configuration wizard that's available at https://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.
You want to set up a hybrid deployment between your on-premises Exchange Server organization and Exchange Online in Office 365. However, when you run the Hybrid Configuration wizard, the wizard doesn't complete successfully, and you receive a Get-HybridMailflowDatacenterIPs is not recognized error message. The full text of this message resembles the following:
ERROR:Updating hybrid configuration failed with error 'Subtask CheckPrereqs execution failed: Configure Mail Flow

The Hybrid Configuration wizard depends on the availability of an Office 365 plan in which it can access the Get-HybridMailflowDatacenterIPs cmdlet. The error message indicates that the subscriptions that you currently have cannot access this cmdlet.
