Enable disabled mailbox

Hi,
 
I disabled some mailboxes in HC, and now i want enable them.When i try to enable them i get message "Some unhandled exception has occurred.", when I try delete disabled mailboxes i got message "Success : Unable to retrieve error description" and the mailxo is not deleted. In the table under email address is "0". 
Is is normal when you disable mailbox that mailbox is automatically deleted?
