Dovecot changes the capabilities it advertises after login. Remove CONDSTORE and QRESYNC; the CONDSTORE is the one messing it up for you. QRESYNC also implies CONDSTORE so you need to disable this one as well. N. What you are doing is disabling CONDSTORE. You can do this on a machine by machine basis by going into the Thunderbird advanced configuration page and toggling: mail.server.default.use_condstore Note, others have reported NOT having problems when using Cyrus..? For me it happens: - Using the same username to login to the same inboxes from separate machines - Both users behind the same NAT (nat timeouts and missed messages a possibility) - Rarely Possibly: - The user that gets affected has been idle for a while (see NAT idea above) - That user is either viewing the affected folder, or recently viewed the folder. Someone needs to catch this thing in the act and get a network trace so that we can put this thing to bed. It happens so rarely for me (and in such large folders) that it's not practical to get a trace. Also note that for me it's mainly a case that I see messages marked unread, when someone else marked them read. This is often fixed by restarting TB (possibly a clue). I don't think I ever need to force a re-download of all messages? Good luck Ed W
