|For the paragraph marks. it depends on which version of Outlook you are using, but in 2007, in 'reply', click on the 'orb' (top left) and select 'editor options', then click on 'display' and remove the ticks from all unwanted formatting marks.|
Most other settings are within the same section so you may find the 'subject' option there. Alternatively, click on 'Tools' menu and select 'Options'.
