We had similiar problem with Dovecot. I have a mail account shared by 3 
users, which communicate with labels/keywords/flags with each other, what 
to do with the message, until it is moved to "done" eventually. Even the 
new and replied status was not shared with a running Thunderbird. Telnet 
and non-caching MUAs showed the changed status fine, hence, it was a 
problem TB getting the changes.

I never pinpointed the problem, never got errors in TB or Dovecot, but 
after I replaced TB with another, newer version and re-created the profile 
anew, the problem went away.

Those three users definitly never changed the TB configuration themselves 
:-) so I really suspect some problem with the cache of TB.
