Outlook doesn't like the POP3 UID values generated by Cyrus. I'm afraid
that outside of dumping Outlook for something else there isn't anything
that can be done about it.

IIRC Outlook Express suffers from a similar affliction.

That is the way IMAP works.

They deleted messages on POP3 server to reclaim disk space since a copy
of the message was stored on the email client. Since *all* messages are
stored on the IMAP server you don't need to delete anything.

Removing the cron job to purge 10-day old messages will partially solve
this problem. Getting your client to think in terms of server-side mail
storage will be the rest of the solution.
