this is what i have....
1.)exchange server 2003

my question is:
Do i have to setup pop3 or smtp server for my clients to access their mail on the outside of my firewall?

This is what i can do....
1.)go to any workstation and pull up the browser and type int http://myserver/exchange this will pull up the owa console, this will work inside the firewall.
2.)if i go outside the firewall and pull up the link for mail i have created on our school webpage, it will not work. Do i have to setup anything like the pop3 or smtp server for this OWA feature to work outside the firewall?

any help would be appreciated....

For accessing email outside of the firewall you have a number of options.

1. VPN. The clients VPN in to your network and then use Outlook in the normal way.
2. OWA. The clients read their email through a standard web browser.
3. RPC over HTTP. Requires a pure Windows 2003/Exchange 2003 environment, plus the clients need to be Windows XP and Outlook 2003.
4. IMAP.
5. POP3 as you have suggested.

POP3 and IMAP are disabled by default in Exchange 2003, you will need to enable them in order to use them. You will also have to change your firewall settings to allow the relevant ports through.


For OWA, the link used needs to be accessible through the Internet. http://myserver will not.
If you have already configured Exchange to receive email from the Internet, then the same address will work. So if your domain has an MX record of mail.domain.com then use http://mail.domain.com/exchange as the address.
However that does mean that usernames and passwords are being send in clear text. If you want users to read email messages outside of the firewall then I would suggest that you purchase an SSL certificate from somewhere like freessl.com and force them to use https://mail.domain.com/exchange instead.
No other services such as POP3 need to be enabled to use OWA.

The MX record is set on your (internet) domain. If your ISP looks after your domain you should call them and ask them to set it up for you.

If you manage it yourself via a web interface then you should look at their instructions for an MX record.

The basic method is that you create a new host of type A with a name (such as mail) in your domain, with the external IP address that your Exchange server is on.
The MX record is then pointed at that host - you cannot have an MX record as an IP address.
