Ghost Mailboxes

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?"

If you have removed Exchange 2003 manually using ADSIEdit. You probably have missed some of the old Exchange server objects.

Only option is to go back into ADSIedit and remove the entires that were missed. These are stored in active directory not the new exchange server. Exchange sees them because the are within the same Configuration partition directory.

Yes.  I have come to that realization.  But is there a quick way to search through ADSIEdit to find these references?
Will SzymkowskiSenior Solution ArchitectCommented:
This really should not be that hard to find. The objects will be stored somewhere in the following location...

Configuration Partition>Services>Microsoft Exchange

I found them.  They we the extended attributes from Exchange 2003 that did not get removed from the user accounts.  Anyway, I was able to script the removal of these attributes from the accounts and all was fine after that.

Thanks to all for the suggestions!
