But thunderbird still synchronizes messages to disk. In "Tools -> Activity Manager" i see: "Syncronizing <AccountName> Bringing folder Inbox up to date" Since i have some large accounts (i.e lots of mails with high volume), thunderbird synchronizes until my disk has completly filled up. I have set "mail.server.default.offline_download" to false and after a while all the individual "mail.server.<server>.offline_download" settings have disappeard in prefs.js However, the syncronizing issue also happens if all the "mail.server.<server>.offline_download" settings are set to false explicit. Reproducible: Always Steps to Reproduce: 1. Turn off (default) Message Syncronizing 2. Wait 3. Messages still gets syncronized Actual Results: Messages still gets syncronized Expected Results: no syncronizing
That's GLODA acting on you ... Go to Edit/Preferences/Advanced/General and switch off global indexing. For more details you can read http://kb.mozillazine.org/Thunderbird_3.0_-_New_Features_and_Changes#Searching Does it help?
I think this issue has been fixed with 3.0b3 or 3.0b4. In the meantime i have upgraded to fc12 and thunderbird 3.0b4 works fine.
