How do i access my work email from home computer

How do i access my work computer remotely from home - (if, however, you use pop3 at work and at home, then you should be able to set up a new account in your outlook email, enter the work pop3 settings, and access your email that way. Presently i can go on to our internet location and use web mail to access my work email, but would prefer to do it through outlook on my home computer. I know how to set up the settings if the isp was the same for both computer locations, but how do i do it when the isp's are different? ) if it is an exchange environment, then you will need the name of your email server and your normal mailbox login (usually your network user name).
