Go into your account settings, more settings, advanced, and check the box that says "Leave a copy of messages on server". Look into setting up IMAP to prevent this from happening. As far as to how to get them back into Outlook.com, hmm that might be pretty difficult. Someone else may have some suggestions.

Then on the next page on the left side, few options down, there is an option to Import email accounts. I didnt see a PST options but there is an option to import from email apps and so Outlook should be recognizable. If you still have the POP mailbox configured then you should be able to select that profile and migrate it. You can also try to open the PST file associated with the POP mailbox in the IMAP profile you configured and drag/drop from the PST to the IMAP folders and see if those sync up with the server.
