I'm not using expunge mode delayed. Haven't been able to get it to work it
just segfaults when expunging.

outlook uses imap and I've tried to access that mailbox using mutt both
through imap and pop3 and I've also tried  squirrelmail. 
The message is there, I can see it on the filesystem but it doesn't show up
after being read.

Since I've never had any similar problems with other cyrus servers, I'm
inclined to say it is something outlook did to that message but I can't figure
out what. If it deleted that message, it wouldn't be on the filesystem.
