When I create a new Outlook profile and re-add POP account, Outlook starts to redownload old messages from POP server if Outlook had previously configured with "Leave messages on server" setting. This occurs even when the very same PST file is used as message store.
I would like to know, where does Outlook keep the information associated with "Leave messages on the server" setting. And if there is a way to "cheat" Outlook into thinking that it has already downloaded these mails (when I use the same PST from it's older install instance).
