Old Exchange mailbox removal process

sidelogic asked
I have migrated from Exchange 2010 to 2013.  The 2010 box is now gone, but I just found a mailbox that is associated to it.  How can I manually remove that mailbox?

Exchange wouldn't have let you uninstall if it had seen the mailbox. Did you rip the server out?

Anyway, you should be able to do

set-mailbox username -database "e2013 db name"

Changing the username to the name of the mailbox and "e2013 db name" to the name of the database on the Exchange 2013 server.

As Simon has stated, if you had originally removed the Exchange server gracefully you would not have any mailboxes left over. However if you have used the manual method initially then you can continue this process manually removing the old Exchange 2010 items.

Take a look at the following link with all of the steps to remove 2010 ADSIEdit.
