Barbara Needham on 9/20/07 said OK, this is the only way I can see to do this; which will take some time but preserve read/unread status. Well, it doesn't actually preserve it but keep track of it.
It involves pretty much what other people have said, but not mixing up your folders. But you would have to export each folder in two batches. Go to a folder, sort by read/unread, then export selected messages as "folder name/read" and "folder name/unread." When they get in to Mail, in the folder name/read mark all those messages as read, then combine the unread and the read into one folder. This would be a long job but it would preserve your folders and status and if you are moving to mail permanently should only have to be done once. Sent mail wouldn't be a problem because you would export the Sent Mail folder as one folder, even though it might not maintain the "sent" flag. It would end up being different from your Mail "sent" folder though. You might want to name it "Mail that was sent from PowerMail." -- Barbara Needham
