I am using version 7 and find that messages I send are not saved despite checking the boxes to save in sent mail

Messages I send are not saved in sent mail despite having checked the boxes to do so.

Hello Len,
what mail account does this issue happen on?
Did this start happening after you upgraded to the newly released version 7? Did you use the RC version before or did you upgrade directly from version 6?

Regards,
Olivia
