NoneType popping up in syncing some folders from Exchange

[chris coleman]

It looks like Dale's mail server oldowa.med.cornell.edu is probably a windows server 2003 host running microsoft exchange server 2003 ( I'm taking an educated guess because it's running IIS 6.0 web server).

Sebastian: is it possible that microsoft exchange 2003 is only going to send back the UIDVALIDITY message after the user has logged in ?  Similar to how google gmail emits a second, changed, UIDVALIDITY after the user has logged in.

Hi there,
a server should send a UIDVALIDITY reponse, which yours apparently did
not. Perhaps that is an Exchange problem with empty folders?

Can you create an IMAP dump via "-d imap -l debug.log" and make that
available to me? I'd love to find out what the server sends. Make sure
to scrub your password/login from it and send it privately to me by
email.

I will add some nicer error message in any case.
