I've heard it several times, and it's always been Outlook. It just seems to go nuts when server changes. No one who has complained about this has ever come back to say if they managed to fix it somehow.
My guess: recreate the account in Outlook and hope for best.
Oh, the other possibility of course: You seem to be using mbox format? If the message's IMAP UIDs change, the POP3 UIDL changes and the messages get redownloaded.
You should at least explicitly set mail_location setting so Dovecot doesn't use autodetection. Also look for Dovecot errors in log file.
