I'm running WLM Version 2012 (Build 16.4.3528.0331) on Windows 8.1 and I moved my store folder to My Documents when I first installed WLM. I have set my 3 Virgin Media email accounts up as POP3 merely because I dislike the way Virgin Media uses Google Mail as their IMAP server and the way that messes up my account folders! And I have set all POP3 accounts to leave a message on the server and to remove messages from server when deleted from 'Deleted Items'. 

But over the last few days, most of my saved emails have disappeared from my storage folders! And some folders show a (1) next to them but still no longer contain any messages. And a folder called Recovered items keeps appearing but it has never had any emails in it!

I copy emails that I wish to save to folders under Storage Folders, rather than moving them. I do this because I thought (a) that it would make my POP3 servers remove all deleted items (including all emails that I have copied to my storage folders and then deleted the originals) and (b) that copies of emails in my storage folders would still be there. Could this be the cause of my problem? If so, why?
