I setup outlook late last night and it pulled off all my email from
the last 10yrs off my yahoo account. I want to keep a copy on the
yahoo sever. I have changed the setting to do this in the future but
I want to get the old messages back on the server.

You can't, except by forwarding them to yourself, which will change every
message. If you didn't want Outlook to delete the messages from the server,
why did you configure it to do so?
