When I try to Empty Trash using the Advanced Interface with POP3, I get the following message:
This Page or Feature is unavailable.
As this is a trial service, this may be a feature that will be enabled later, or you may be trying to access something which is only available in another mode (if you are using POP3, try IMAP). If you have received this message we would be grateful for your feedback about what you did to get here via our beta testing feedback forum.
This has just happened to me. When I returned to see what, if anything had happened I was still in the Trash folder the same number of messages were there but they had all been "zeroed", had todays date and 0k size.
