I need to try and restore a deleted mailbox in Exchange 2010 on an SBS2011 box for a user account that was accidentally deleted today. At present nothing shows in Disconnected Mailboxes. I have checked and the Exchange retention policy is set at 30 days. I have found the Clean-MailboxDatabase command that may make the mailbox show up, but am unsure of the correct syntax to use. Any help greatly appreciated.
