Using Outlook via the Internet

If you are using Microsoft® Office Outlook® 2003, you can connect to the
computer running Windows® Small Business Server through the Internet using the
feature called RPC over HTTP. This means you can remotely access your server
e-mail account from the Internet when you are working outside your
organization’s firewall. You do not need security-related hardware or software
(such as smart cards or security tokens), and you do not have to establish a
virtual private network (VPN) connection to the server.

Comparing RPC over HTTP and Outlook Web Access

When using RPC over HTTP to access your mailbox, you get the full
functionality of Outlook 2003. For example, you can work offline, use Microsoft
Office Word 2003 as your e-mail editor, and easily organize your mailbox.

To use Outlook via the Internet

Ensure that the following requirements have been met on the client
computer:

Verify that the computer is running Microsoft Windows XP Service Pack 1 or
later

• Click Start, right-click My Computer, and then click
  Properties.
  The version of the operating system and service pack is
  displayed under System. If you do not see a service pack version, there
  is no service pack installed.

Verify that Windows update Q331320 is installed on the computer (not
required if you are running Windows XP Service Pack 2 or later)

1. Click Start, click Control Panel, and then open Add or
   Remove Programs.
2. Under Currently installed programs, search for the item Windows XP
   Hotfix (SP2) Q331320.
3. If the item is not present, go to the Microsoft Web site
   (http://go.microsoft.com/fwlink/?LinkId=18651) and follow the instructions to
   download and install it.

Verify that the computer is running Outlook 2003 or later

1. Open Outlook.
2. Click the Help menu, and then click About Microsoft Office
   Outlook. The version number appears at the top of the box.

Verify that the computer trusts the certificate used by the server

1. Open Internet Explorer, and then in the address bar type:

   https://host.yourdomain.com/remote

   • If the certificate is trusted, a certificate warning does not appear. In
     this case, continue with step 1 under Ensure that you have an Outlook profile
     configured for the server.
   • If the certificate is not trusted, a warning appears. Click View
     Certificate, click Install Certificate, and then follow the
     instructions.

Ensure that you have an Outlook profile configured for the server

1. Click Start, and then click Control Panel.
   • If you are viewing Control Panel in the default Category view, switch to
     Classic view, and then double-click Mail.
   • If you are viewing Control Panel in Classic view, double-click Mail.
2. In the Mail Setup dialog box, click Show Profiles. If your
   profile appears in the list, select your profile, click Properties, click
   E-mail Accounts, select View or change existing e-mail accounts,
   and then click Next. If your profile does not appear, open Outlook and
   follow the instructions to create a profile before proceeding.
   • If Microsoft Exchange Server does not appear in the list, the existing
     profile is not associated with a Microsoft Exchange Server e-mail account. Click
     Cancel, and then click Close. Continue with step 3 to add a
     profile.
   • If there is an existing Microsoft Exchange Server profile, continue with
     step 3 under Configure the computer for RPC over HTTP.
3. Click Add. The New Profile dialog box appears.
4. In the Profile Name box, type a name for the new profile, and then
   click OK. The E-mail Accounts dialog box appears.
5. Under E-mail, select Add a new e-mail account, and then click
   Next. The Server Type dialog box appears.
6. Click Microsoft Exchange Server, and then click Next.
7. Continue with step 4 under Configure the computer for RPC over HTTP.
