It seems it is the problem of Outlook, NOT cyrus problem.
I still have the same problem of using Outlook for a very IMAP quota since 
the outlook uses mailbox file to store the IMAP folders, including INBOX.
Office 2003 Outlook is better to handle large file in my own test, but it is 
still very slow to fetch mail from IMAP server.
My suggestion is to distribute the mails in INBOX to several IMAP folders 
and this will divide the single large file of INBOX mailbox file on the 
client PC to several relatiively smaller mailbox files.
This may reduce the CPU and RAM requirement and hence a faster mail 
checking.

Hope this helps.

Patrick
