Automatic Archiving doesn't seem to work. None of the message in my Yahoo online account are removed. Why is this/how can I fix it?

First I did read the other ‘solutions’.

I have selected ‘ALL MAIL FOLDERS’, Enable and Ask are checked, clicking Perform Archiving doesn’t do anything. Clicking Apply and Send and Receive all does nothing. No files are deleted from my online account, no error message appear, nothing happens.

I have already answered in the other topic. Anyway, feel free to contact me at wilson@emclient.com - I will send you further instructions.
