Contacts missing after changing from webmail to imap

After my Outlook.com servers were changed, I created new imap accounts replacing the original webmail accounts by following the instructions in Windows Live Mail and Outlook Mail . I've been pretty happy with the change, except today I realized I don't have my contacts anymore. I couldn't even find the Contacts folder (I thought it had been in Users>Larry>App Data>Local>Microsoft>Windows Live Mail). I assume I can still find it in an old backup. How can I get my (old, missing) contacts to work with the new imap accounts?
