I don't know why it's not working, but I suggest you not name folders with -, _ or any other special characters. You can only copy eml files with drag and drop into a folder that appears in the TB folder pane - not a folder that you see in File Explorer.

The folder 2019-03-07_test - 2 shows up in both TB and File Explorer. Do you think it will work?

I will try a folder name without any special characters and see if TB creates a folder that File Explorer can see and not just 2 files. I will let you know.

I tried using TB to create a folder named aaa and TB did not create a folder that File Explorer can see. TB did create the 2 files.

Any more suggestions?

OK this is how I finally got it to work. There must have been something wrong with the Inboxes in the old profile because this worked.

On the old Profile I:

 o  created 2 new local folders to copy the 2 inboxes  and 
 o  copied the contents of the 2 inboxes for my husbands 2 email accounts into the 2 new local folders.

On the new profile I:

 o  set up the 2  email accounts and options
 o created new local folders to match what he had on the old profile
 o  used File Explorer to copy the files from the old profile to the new profile

I want to thank sfhowes for all the help.

I'm glad you got it working, but do the images now appear in messages with the new profile?

Yes they do. Thanks again.
