Outlook getting 'unexpectedly terminated' errors

[Mike Eggleston]

Is there a timeout I need to tune inside cyrus so that my outlook users
do not get the 'unexpectedly terminated' errors? I get these errors
when on my workstation outlook is simply idle. I received a call from a
user today that is getting these same errors trying to create a folder
with their account on the cyrus imap store. The user tries to create a
folder, gets the 'unexpectedly terminated' error, tries to create the
folder again, gets an error saying the folder exists (was created by the
first create attempt), finally must subscribe to the newly created folder
(something used to auto subscribe, now doesn't).

The user has Microsoft Office 2007 with SP1.

I have no problem with cyrus closing idle connections. Maybe I'm closing
connections too quickly?
