I want to access my work outlook express email at home
It depends on what your company has set up. Some companies have what's called 'Outlook Web Access'. You go to a site and login, and can do all of your email right there. You don't use outlook itself, but a browser version. So, ask if you have this set up, and if so get the URL info and start working from home! if you can access your work email within outlook, the answer is no. A very easy way to have all your messages forwarded to your home outlook is to create a rule from your work computer. Do this: (may vary somewhat depending on the OS you are using) in outlook go to tools/ rules/ create new rule and create a rule so all mail in your inbox or specific senders is forwarded to your home address.
Such as all mail addressed to (your work email address) forward to (your home email address) You can always delete the rule later.
