Your PocoMail email client’s “Special mailboxes” are a type of virtual mailbox. The messages are not actually located or stored in that folder, they just appear to be. The “messages” act as a sort of shortcut 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) the message are actually stored in, you can process it and the messages will be found in the target mailbox created by Aid4Mail.
Should you require any assistance, please don't hesitate to contact the help desk.
