Does anyone have a neat way to backup the Sent folder from outlook.com? The Inbox can be copied easily to Windows Live Mail using POP3, but without IMAP I can't see any easy way to make an offline backup of the Sent folder.

I guess one possibility would be to bcc myself on all emails and then move emails from myself into a Sent folder in WLM with a rule, but I can't see any way to automatically bcc myself in outlook.com.

So does anyone know how to easily make an offline backup of the Sent folder?
