we have exchange 2010 server standard with 3 database and when I tried to create 5 db I was not able to mount it as standard only allowed 4 db. I've deleted additional DB and files associated with it however when i am trying to create new mailbox I still see deleted DB name as an option and my backup software also see a record on another that phantom DB and give me errors that files don't exists.
How do I remove that phantom record.
also I moved all of the user mailbox from you default "Mailbox Database xxxxxx " which was created at initial install time, but when I try to delete it I am getting an warning that its not safe to delete. what is the best way to move and rename it or delete it ?
