Outlook Express as default mail program

[Guest]

I just had a new computer installed at work. The old computer as well as my
laptop and my home desktop open "My e-mail inbox" with an explorer window.
The new computer tries to open my hotmail account using outlook express.
Where do I need to go to change that default? I've tried changing it under
internet options, but the change won't stick (and explorer isn't an option).
