Shared folder fiasco

[Tom Plancon]

Hi folks,

I'm running an email server for 40 users on cyrus-imad 2.6 on CentOS 6, 
with postfix 2.2.6. Our email client is Thunderbird. I tried to set up a 
shared mailbox using a howto found here: 
http://wiki.linuxwall.info/doku.php/en:ressources:dossiers:cyrus:shared_mailbox. 
Based on that info, I set altnamespace to yes in imapd.conf, and that 
caused problems for the Tbird clients; it acted as though it had never 
seen the user's mailboxes before and needed to reload all of the 
existing email headers in all folders!  That was especially true for the 
Sent folder which Tbird could not find for a while and kept throwing 
errors, although it sent the email. Also the display of the users Inbox 
changed in the Tbird folder listings to appear as a "subscribed" folder 
rather than the user's INBOX.

After about 36 hours things settled down and is now behaving normally 
for most users, however I have 2 users that cannot see the contents of 
their INBOX. The email is there, and they are receiving normally, but 
just not visible in Tbird. All other subfolders are there and the 
contents visible.

I don't see anything unusual in maillog for the 2 users. I've tried 
completely removing their Thunderbird installation then reinstalling, 
inbox contents appears initially then disappears! Any thoughts as to 
what's to do here are greatly appreciated! Thanks!
