Check your settings under View / Folders

It is currently set to view all folders

Do I need to re add the email accounts to thunderbird for those folders and messages to show up? I was making the assumption that all the account configuration should come over with the profile restore. Am I correct in that assumption?

What did you restore from? Program used?

Of course you don't need to add all emails account again. Can you give us a screenshot of your files and folders from profile / ImapMail / account-server / *.*

I am just copying the profile from one drive to another. In the screenshots, D:\ is on the HDD i have mounted in a drive dock. On the new workstation, installed thunderbird, launched with default profile, closed TB, and emptied the default profile created. Then copied the contents from the old roaming profile from the old HDD to the roaming profile on the new installation of TB.

There are both IMAP and POP accounts in the old profile of TBird

I cant find anything apparently wrong. Did you use the same drive-letter on the old pc?

Not sure, this was from a pc that had some sort of OS failure. They brought it to me with the main hopes of recovering the email to a new PC, but have been unsuccessful. It is so strange that I can see all the messages, and that I can even open and read them by clicking on the files themselves, but Thunderbird just won't see them. What is really odd is that the address book info is there in TB, but nothing with the email accounts or folders/messages. Thank you for putting another set of eyes on this, I realize that the profile backup and recovery is generally a pretty simple process, something must have hooched this profile when the OS problem occured.

As you can see the folders you could try to use an add-on ImportExportTools by using that you can import all mbox-files (files with no extension)
