So I have this client whose Exchange 2003 server crashed. Rather than rebuild and restore they decided to just start fresh with Exchange 2013. So the used ADSIEdit to remove the old Exchange Organization from AD because they could not get the /removeorg to run from the 2003 CD.
Today they installed 2013 and that seemed to go fine. EXCEPT, now they see ghost mailboxes from the old server. They are all listed as legacy mailboxes. They can't delete them - even in EPS. There is no database associated to them. How do they get rid of these "ghosts?"
