Cause

This issue occurs if you try to change a mailbox type by changing the source Active Directory object after the mailbox has been provisioned in the Office 365 Dedicated or Office 365 ITAR environment.  

The mailbox type is determined by the Microsoft Managed Services Service Provisioning Provider (MMSSPP) service when the mailbox is first provisioned.
