I use Outlook Express for all my e-mail. Unfortunately so does the rest of the family. Is there a way of receiving and storing MY e-mails so that the rest of the family can't access/read them? In other words, I could do with a separate inbox
Yes. File / Identites / Manage Identites. You'll need to set up your email again, unless you keep the Main Identity, but you can just copy the settings across. You can password it too.
