Mailbox restore - MapiExceptionNotFound: Unable to open message store. (hr=0x8004010f, ec=-2147221233)

Hi All,
Help please!
I have an Exch 2010 SP2.

I restored "application" from Windows backup -> successful. And I created recovery database (RecoveryDB), and mounted -> successfull.

I could not restore mailbox from RecoveryDB.
I want to restore "kmc250sza" mailbox from RecoveryDB, but I have an error:

Couldn't connect to the source mailbox.
+ CategoryInfo          : NotSpecified: (0:Int32) [New-MailboxRestoreRequest], RemotePermanentException
+ FullyQualifiedErrorId : F6FB8A18,Microsoft.Exchange.Management.RecipientTasks.NewMailboxRestoreRequest
 
The command:
New-MailboxRestoreRequest -SourceStoreMailbox fbc2acd5-31b8-48e9-88f4-564ea2cb81ca -SourceDatab
ase "RecoveryDB" -targetmailbox admincspeto -AllowLegacyDNMismatch -verbose
