If you can manage to find the files the outlook saves on your hard drive and copy those, you should be able to import them on a different computer. (File, import, Messages) in Outlook.
Outlook stores my inbox here for example:
C:\Documents and Settings\[User name]\Local Settings\Application Data\Identities\{4D138D6C-6D00-472A-B39C-A6CFD41C98D9}\Microsoft\Outlook Express\Inbox.dbx
Hope this is helpful. As for accounts, I'm unsure. but you can always set an account back up, you don't lose anything.
