A customer running an Exchange 2010 SP3 UR15 multi-role server had issues moving mailboxes between databases.
The error experienced was as follows:
Get-Mailbox "mailboxname" | New-MoveRequest -TargetDatabase "Mailbox Database Canada" -BadItemLimit 10
There are no available servers running the Microsoft Exchange Mailbox Replication service.
+ CategoryInfo : NotSpecified: (0:Int32) [New-MoveRequest], NoMRSAvailableTransientException
+ FullyQualifiedErrorId : C7FE28BB,Microsoft.Exchange.Management.RecipientTasks.NewMoveRequest
Running Test-MRSHealth cmdlet to test the Mailbox Replication Service (responsible for processing mailbox moves) returns the following error on the environment.

Description:
The mailbox GUID of an external system mailbox ('Mailbox - SystemMailbox{1c3fa654-fe01-4041-a3a6-0444ca10f96c}') does not match the information in the Active Directory for the mailbox. The existing GUID ('8c0c971d-c5d7-495b-aff7-53356904789a: /o=Exchange/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=SystemMailbox{1c3fa654-fe01-4041-a3a6-0444ca10f96c}') has been replaced with the expected GUID ('ed55827e-7cdd-466e-9421-a0dbce5f6486: /o=Exchange/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=SystemMailbox{1c3fa654-fe01-4041-a3a6-0444ca10f96c}').
The GUID of the SystemMailbox no longer matched the GUID of the Active Directory mailbox at the customer site.
To restore this, we ran "Setup /PrepareAD" from the Exchange 2010 SP3 setup media. This restored the Exchange SystemMailbox association with Active Directory.
After running Setup /PrepareAD on the environment, we were able to move mailboxs again.
