regaridn connect to domain

sir
plz let me know
how can i connect to my company domain my linux machine.
and get mail as i get in outlook,
n others can c me in network.

i guess you mean:
You have a linux box and company network.

  1. ask your admin for IP-Addr, netmask and gateway
    use your distros admin tool for that (or ifconfig and route, see man-pages for more info)

  2. ask for pop3/imap server addr, (perhaps additonal security settings)
    start thunderbird and set the server settings
