Comment 21 for bug 1068921

Is somebody with the bug willing to test whether it's related to the offline message size limit? Open the Mail Server properties for a folder showing this problem (right click on the mail server, select "Settings...", select the "Synchronization and Storage" settings, and check whether you have "Don't download messages larger than x KB" checked.

If you do have it checked, try un-checking it and see if the problem goes away - your client should download the large messages one more time and then stop.

I've been looking at the log file on the Launchpad bug, and that log only shows us downloading each of the large messages once.
