When I left my old company, I mistakenly copied my outlook 2003 OST file and didn't realize that it wasn't the usual PST file. Does anyone know of a way to convert it to a PST file? Or have other suggetions?

From my research, MS doesn't provide a solution to this. There is 3rd party software (officerecovery.com), but I found it didn't convert every email properly. I was able to get my calendar and contacts out OK, but only about half the emails, and the attachments aren't accessible.
