Couldn't connect to the source mailbox Exchange 2013

Hello !

I'm trying to restore a mailbox with the following command:[PS] C:\Windows\system32>New-MailboxRestoreRequest -SourceDatabase "Exchangedatabase" -SourceStoreMailbox "d205b4d5-0884-4a7d-b321-7be547956346" -TargetMailbox "test" -AllowLegacyDNMismatch

However after running this command I’m getting the following error message:

Couldn't connect to the source mailbox.

    + CategoryInfo                 : NotSpecified: (:) [New-MailboxRestoreRequest], RemoteTransientException

    + FullyQualifiedErrorId : FF8B8A76,Microsoft.Exchange.Management.RecipientTasks.NewMailboxRestoreRequest

I have no idea on how to solve this issue. I hope someone can help me out.

Kind regards,

Jelle
