Your PocoMail email client’s “Special mailboxes” are a type of virtual mailboxes. The messages are not in that folder. It just has an appearance of the messages. The “messages” act sort of like a shortcuts so that when you see the messages in the index grid and click on one, it is actually opening the message from another PocoMail mailbox.
If you convert all your mailboxes, the messages will indeed be processed! If you know which mailbox(es) they are actually stored in, you can process it and the messages will be found in the target mailbox created by Aid4Mail.
If you experience any issues, please don't hesitate to contact us by raising a ticket.
