How do I move emails from a folder to the inbox in Outlook?

I created a rule that moved emails from a specific person to a folder I
set up for that purpose. Now I deleted the rule so all the emails are once
again going to the main inbox however I want past emails from that person
in the inbox also. I don't know how to delete the folder without deleting
all the emails inside it also.
I am using Outlook 2003 on Microsoft Exchange
In general in windows I believe there should be a way to delete a folder
and have all its contents simply move into the next location in the file
path
