If you have a Microsoft exchange account then you can follow the advice above.
If you use Outlook at home and don't have an exchange account then you can still retrieve emails after they have have been deleted from the deleted items folder.
This is because when you delete emails from the deleted Items folder, they disappear from outlook but are still stored in your PST file. Its a bit like when you delete a file from your computer but its still actually stored on your hard drive until it is overwritten.
This is why Outlook needs to periodically compact the PST file to regain the space taken up by deleted items.
If the PST file has not been compacted since you deleted the emails from the deleted folder then you can retrieve them by corrupting the PST file and recovering the email using SCANPST
Here is guide with step by step instructions on how to do this and I would always backup the pst file by copying it to another folder before trying this.
I dont think you can retrieve emails deleted from Deleted Items folder. Anyway, you can see if this can help you http://www.groovypost.com/howto/microsoft/ie/recover-deleted-email-in-microsoft-outlook-from-any-folder/

You're in luck. Files deleted are still recoverable unless you pressed Shift+Delete (the permanent delete shortcut) to remove them.
The easiest way is to download the Microsoft Fix It tool, which automates the process of recovery.
If you want to manually recover the emails launch the Recover Deleted Emails tool from the Tools menu.
