Unable to edit "Delete from server" in Samsung Email app

Bob Hawkins

I have a Galaxy Tab A running Oreo 8.1.
I wish to check or change the option selected in "Delete from server" but cannot find a way to access it in the Samsung Email app.
Going to Settings>Cloud and accounts>Accounts and tapping Email shows the email account, "Sync account" and a tab, "REMOVE ACCOUNT" only; nothing exists to take me to the set up.
