Welcome to the Support Communities!
I think you are asking about "Strikethrough? "
In your email message, select the word or words that you want to edit.
Right click or Control click on the selected text.
From the menu, choose Font > Show Fonts
Select the second item on the toolbar, which is Text Strikethrough
Choose a single, double or color line
I hope this information helps ....
Have a great day!
