Office 365: Remote Move Request: Exception has been thrown by the target of invocation

Here are some field notes from a recent case on a hybrid Exchange 2010 deployment with Office 365 issue, The error we saw when trying to do a Remote Mailbox Move from on-premise to Office 365 was:

Remote Move Request: Exception has been thrown by the target of invocation

 

This can happen if you have an Exchange Hybrid deployment configured and attempt to create a new remote move request from on-premise to the cloud (Office 365).
