you know, i never paid attention to the messages remaining. i just thought the messages were removed after a certain amount of time. huh, guess i was wrong. the info is here: http://office.microsoft.com/en-us/ou...804201033.aspx
, with a simplified excerpt below.
>hover mouse over 'purge' from the drop down menu
>select 'purge options'
>check the box 'purge items when switching folders while online'
now, whenever you mark a message for deletion in outlook, it will be removed from outlook when: 1) you are online, and 2) you switch from your inbox to another folder
