You can access mail from the same account on different computers through MS Outlook only if you have a mail server running on your network such as Exchange. Otherwise, when mail is downloaded, it is saved in a PST file that is only accessible by a single Outlook client.

You can share parts of a PST file such as the calendar by using MS Net Folders. Check out

You cannot share Outlook Express at all between multiple computers.

If you will use MS Outlook and roaming profiles, you can save your PST files on a shared folder (with correct permissions) and you will able to work with your personal e-mail in any location/computer on your network. You must use all the time the same logon account and logon at one computer at a time.
