Setting up your Email is a different matter and depends whether your Email
is provided by your ISP, a webmail service eg.(Google, Yahoo, etc.)
or from your own server. Also which email client you wish to use ("Microsoft
Outlook", "Mozilla Thunderbird", or some other client). Also for this you need to know the email
provider's server settings along with your username and password and whether you are using
the pop3 or IMAP protocols
In a business context this could mean setting up several different accounts on one machine
one for each employee who needs it
