I tried the repair folder trick, and it seemed to work. But the operation reset the folder settings; I like to see additional columns such as "Recipient". As soon as I set that, I noticed the issue started again.
Win7 (all updates applied), x64. Sorry I didn't test on a new profile, and the timing of my change and noticing the issue may be coincidental. But I figure every bit of info may help you. What also should be mentioned, is that there are known IMAP problems with recent version of MS Exchange. So much so, I ended up installing the DavMail gateway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074260 Title: Thunderbird heavy IMAP traffic downloading messages To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1074260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
