This article explains an option of how to recover email items that were removed from the Deleted Items folder.
Unless you have your Deleted Items folder set to empty when you close your email, and you have closed it. You should still be able to find the deleted Inbox, and or items that were in it. You can then move them out of that folder like you would move files from any other folders.
