I have set up and used for many years a message filter to move a small (50-60kB) daily newsletter from Inbox to a specified folder that contains only these messages and is frequently cleared, compacted and/or repaired. Yet very often, every week or so, there is an error message that the filter failed because of problems with the destination folder. This folder is in the same account as the Inbox.

Why? How can I correct this?

Do you have other filters that do work? And on this same account?

Does it use POP or IMAP?

try creating an exception in your anti virus for Thunderbird mail folders. Often these error are caused by mail files being scanned when Thunderbird tries to use them. (File contention)
