Hi KDB9000,
When using pop in outlook do this:
Go to>tools>email accounts>view or change existing account
click on "next"
highlight the account you want to change
click on "change"
click on "more settings"
choose the "advanced" tab
click on "leave a copy of messages on the server"
click on "OK"
click on "next"
click on "finish"
Outlook will now download a copy of the message and leave a copy on the server

I hope this helps.
Regards,
Del
