Outlook DOES store some kind of cache of IMAP mail in a PST. And that PST 
is always located in the Local Settings directory, regardless of your 
system-wide default location of PSTs.
I don't know what happens when this cache PST reaches its 2GB limit...

Related: I sometimes have people complaining that some emails don't show 
up in Outlook (2003) but are listen on webmail (Squirrel). Typically, 
users have 'hide messages marked for deletion' set. Changing that to show 
all messages makes the 'missing' mails visible, but they are then not 
marked for deletion.

(Running the etch-backports 1.0.15 version of dovecot-imapd currently)

This looks like it's an Outlook problem, but if a workaround at dovecot's 
side would help, I would be very happy.
