That program is defunct Rob and is no longer supported by MS. It was replaced by a cloud based program called Outlook.com, I think

If you were not made aware of a pw, all the email addies were probably set up with the same pw. If your office girl knows it all you have to do is set up your email account on one of your working computers and log in from there.

When you get your new computer, you can set up the new outlook program or maybe even continue to use Express if you have the software to load it up. You could also go to something like Thunderbird. Doesn't make much sense to continue using Express.
