Running Thunderbird 115.12.2 (32-bit) I have setup a Message Filter to automatically transfer an email to a local folder. The transfer is not working even when I start the filter manually. I then tried to right click on the email and copy it to the local folder, but that also did not work. I thought the problem might be with the local folder so I deleted it. When I attempted to add a folder with the same name, I was told that a folder with that name already exists. Very confusing. I have several other similar filters that work properly. Is the any log information that could provide a clue to what is not happening.
