I have used TB2 for some time and everything worked well. I recently did a complete reinstall of Windows and installed TB3. I use TB to access an IMAP email acocunt from Fastmail. Emails are moved (both automatically and manually) into different folders and I use the ability to star messages to indicate when I have finished working on an email. Non-Starred messages are then collected in a number of Saved Searches to be worked on.

Since the first installation of TB3 messages that have been correctly starred have suddenly appeared as non-starred, sometimes this is a few random emails, but most times it is 20-30+ emails from the same folder that appear as non-starred. After some time the problem will correct itself if I ignore it.

The most recent occurrence of this resulted in about 40 messages that had been previously starred (some many months ago) appearing in TB as non-starred. However all of these was still correctly flagged (starred) on the Fastmail web interface. As a test I then rebuilt the index for the folder that was affected and the emails returned to being correctly starred. (Folder propertied -> Rebuld Index).

Reproducible: Sometimes

So it sounds like a corruption of the local DB with upadte of FLAGS over imap.

Are you running extensions ? (can you disable them and see if your issue is still present)

Would be nice to have clearer and simpler steps to reproduce.

The only extension I was running was the British English Dictionary. I disabled that earlier today and the problem has just happened again.

It is very difficult to give clear/simple steps to reproduce as this error seems erratic. I have no idea when it will happen and when it does I have discovered that I can correct it by rebuilding the index for the affected folder, of I can wait and persumably next time TB reindexes the folder the problem disappears.

Let me know if I can help with any other info, or if there is anything else I can try to diagnose the problem better.

This sounds like an other manifestation of the condstore issues we've been seeing. You might try a 3.01 candidate build from here - http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/3.0.1-candidates/build1/

If this is a condstore issue, I believe turning off the use of condstore might help - https://bugzilla.mozilla.org/show_bug.cgi?id=530551#c3, or you could try generating an imap protocol log when this happens and sending me a log https://wiki.mozilla.org/MailNews:Logging - [e-mail]

David,

I upgraded to 3.0.1 and this made no difference. In fact it made things worse as many messages appeared as unread as well as not-starred!

I have now turned off the use of condstore and that seems to have resolved the problem. I will update this ticket in a few more days when I am confident that the problem has not re-appeared.

Sandy, you could turn condstore back on and try a build with a fix for this bug - http://s3.mozillamessaging.com/build/try-server/2010-01-20_15:[e-mail]-1264029848/[e-mail]

It's basically 3.01 plus a bug fix. If you do try it, and it helps, please let us know. (or you could just leave condstore support off).

The build above is installed and condstore turned back on. I will test and let you know.

Comment 7

[Sandy Matheson]

I have been using this build now for two days and it seems to have fixed the problems. Condstore is turned back on and I have had no re-occurance of the problems.

Many thanks for this bugfix.
