Therefore, you should no longer use the old Hybrid Configuration wizard. Instead, use the Office 365 Hybrid Configuration wizard that's available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.

The Exchange admin center doesn't have the option to move only a primary mailbox. To do this, you must use the New-MoveRequest cmdlet.
To move only a primary mailbox, follow these steps:
