After you've completed deleting an email, it will be automatically sent to the Deleted Items folder. There, you can choose the "Recoverable Items" folder and drag and drop the deleted items from it. You should be able to find the deleted items in the recoverable Outlook folderin a few minutes. After this, you can drag and drop them to the inbox. In case you've accidentally moved them to the Recoverable Item folder, you'll be unable to restore them.
