How to set Exchange 2003 for POP3 / IMAP and OWA
Posted on 2007-12-04
Just set yesterday new 2003 SBS R2 box with Exchange. The domain name is "domain_name.lcl", server name is DOMAIN, I can send and receive emails, but only from workstations which are part of the domain and connected to Exchange via Outlook. To set workstations to communicate with Exchange I use DOMAIN.domain_name.lc as server address and then Outlook can find user in AD. But what will be the mail server name from outside? There are people with Macs and Windows XP Home which cannot be a part of domain so they should access it using POP3 or IMAP. Also, there are some blackberries/smartphones they want to receive email as well.
This new server replaced old W2K server with exchange and uses the same IP address, I did not change any DNS records.
First of all, I don't know what will be POP3/IMAP server name. I know what the IP address is, and I am sure that mail.domain_name.com DNS record contain the right address of the server as it was receiving email before I switched the boxes. I assume that probably I did not set proper things on the server.
Can you please walk me through this process? At least (if it easier) I can enable OWA so they can send and receive emails from the browser, and then I can work with enabling POP3/IMAP...Eighter way, I need one of them up and running before the users kill me :-)
