No solution here, but I am probably having the same problem with 1.0alpha4.

I'm trying to switch to imap from pop3, so I set up dovecot on my 
Slackware 10.2 mailserver.  I'm very new to imap, so I figured my 
configuration was wrong.  If our symptoms are the same, maybe our setup 
errors are as well.

The problem... while Thunderbird and Outlook are OK, the Inbox doesn't 
show in Outlook Express.  You can click on the Imap Folders button, 
select the Inbox, click on the "Go To" button and the Inbox will appear 
until you shut down Outlook Express.  Next time you fire up OE, no 
Inbox.  Other than that, it all works as expected.  I haven't 
torture-tested the setup yet though, I wanted to set up one of each 
client and get the basics running before doing that.  Are your symptoms 

Here is my dovecot.conf less comments...
