Converting from POP3 to IMAP on Outlook

I recently got an iPhone and was instructed to set up the email functions on it using IMAP. I use Outlook 2007 on my PC and have it set up for POP2 with a PST file. I added another email account in Outlook and set that up to use IMAP. I want to move my Inbox, Sent Messages, etc. from the PST file for POP3 to the IMAP PST file. I was able to copy the Inbox to the IMAP PST but I cannot copy the Sent Items. I get an error message indicating that Sent Items already exists but I do not see it. I need to keep my messages and whatnot but do not want to have to manage two separate PST files. How to I move everything from the POP3 PST file to the IMAP PST file?
