Hi again,

I am no expert and I do not know the correspondig rfcs without looking
them up, but that is what my experience is.

This is what I can remember:
If I (somehow) have downloaded from the pop3 server but not flushed
emails, they stay at the server which I have prooven by telneting to it
and asked the server myself. I had to tell fetchmail the "fetchall"
keyword which is "Fetch all messages wether seen or not" to get them,
too, and not only new, unseen mails.
...I don't know how outlook behaves at such, but this shows pop3 _has_ a
seen state.
