Using Outlook 2003 to access Exchange 2003 mail both at home and at work.

Ok, I'd like to be able to use my Outlook client on my laptop (that I use at work) at home, to access my work (exchange) email, and my other mail accounts, all together. I don't really like Outlook Web Access as it's slow, and some features like the calendar are awkward to use. Plus the fact that Outlook Web Access doesn't collect mail from any other accounts that you've told proper Outlook about. To clarify, accessing my other pop3 mail is not a problem - don't need help with that! - just the Exchange mail.
I know there are some similar questions to this one, but I'm not that much of an expert - in fact -I'm not an expert!
The OS is Windows Server 2003. We use exchange for internal and internet mail.
Neither pop3 nor smtp services are enabled on the server at present - do they have to be? What do I have to do in Outlook to point it at my work server from home? Do I need to do anything with either the router at work or the router at home? Any pointers here would be greatly appreciated!

    "We use exchange for internal and internet mail"
    "Neither pop3 nor smtp services are enabled on the server at present - do they have to be"

    first thing u should understand that POP3 and SMTP are two different protocols and used for different purposes, POP3 used for fetching your emails from POP3 server and SMTP used to send emails to other servers.

    to be able to exchange email from internet you have to enable SMTP or you would not be able to send or receive emails to the internet.

    the second thing how u can access ur emails from home using Outlook Client, there are many ways u can configure your exchange account in outlook as a pop3 account and use it in office or home to access your emails, does not make any difference at the client side but u have to make sure that pop3 virtual server is running in exchange and u also open port 110 on your firewall to allow exchange to listen pop3 requests from outside of your LAN. but for sending emails from office u should use exchange as your SMTP server and from home u might have to use your ISP's SMTP or one of your yahoo or google account because might be your ISP blocks SMTP traffic to your Exchange.

    the actuall solution which suits u is RPC over HTTP but it needs some complex configurations. i suggest you to use outlook for other accounts and OWA for your Exchange Account. if still u need help on RPC over HTTP please tell me i would refer u the articles "How to configure RPC over HTTP"

    As long as you meet the requirements for RPC over HTTPS, you would seem an ideal candidate. The main problem with POP3 is that it is too easy to suck all of your email off the Exchange server.

    RPC over HTTPS has very strict requirements:

    Exchange 2003 on Windows 2003, part of at least a mixed Windows 2003 domain with at least one Windows 2003 GC/DC available.
    Client MUST be Windows XP SP2 or higher, with Outlook 2003.

    If you meet those requirements, then you can use RPC over HTTPS.
    The configuration on the server is a little fiddly, but I have covered it all on my web site:

    If you cannot meet those requirements above, then you are stuck with the other technologies, including OWA, IMAP and POP3. IMAP is probably the closest to Outlook/Exchange combination, as in it is a server based technology and will leave the email on the server. You will only get email though, no calendar etc. IMAP is not enabled by default on Exchange.

    Also viable to consider building a hardware or software VPN route to the office, and if DNS and other name resolution is in good order (you can ping by server name) then outlook will be non the wiser, it will just function a little slower.

    In this case consider using cached exchange mode if using OLK 2003, or manually created OST file structure for previous versions of Outlook.
