If i install Exchange server on Windows server 2003 - create email accounts etc etc could i relate those email accounts to people who are running on Win XP pro machines in order for them to use the email within the network and not externally if so could someone advise or point me where i could read up on this?

Thanks

If you install exchange 2003 on a Server 2003, and install the Service pack for exchange, you could use computers running windows xp to get to the email accounts that you set up. You would have to use a mail client to access the mailboxs for example you could use Microsoft Outlook, just configure it to get the mail from Exchange. There is extensive help on this at Microsoft. Look for white papers on how to set it up.

Hope this answers your questions.
