Review for ImportExportTools by tekflight
Rated 5 out of 5 stars
I suddenly was not able to open many emails - they would be blank but you could see the html source and most graphics just showed the code. I used the tool to export and then re-import all my folders and mail and although some graphics got lost, my mail was there and functional.
