Hi @Lindy Overlander ,
According to my research, the creation time is recorded in the Sent folder and can be seen in the message list, while the delivery time is recorded in the email header and can be seen in the reading pane or when you open the email.
This can be viewed in compact view. (View > Change View > Compact)
In addition, there is another way to see when the original was created, you need to use a single view to see;
Go to View > Change View > Single.
The received column shows the original creation time.
