Unable to export messages to CSV

[pietercox]

Hello, Perhaps I'm doing something wrong. Export to Text and other formats are fine, but I have no success with CSV. The ouput produces just six columns: A - The subject text B - Sender's email address C - Recipient's email address D - Date sent E - Blank F - Subject:

To be clear, column F only contains the text "Subject:"

I'd be very grateful for any pointers to what I should try - or confirmation that this just isn't possible. Many thanks. Pieter
