How to configure Outlook 2003 on Windows XP Pro to access Shared Exchange services.

Escape Key supports the latest technology for accessing Microsoft Exchange called RPC-over-HTTPS. The primary benefit of this technology is secure access to our Shared Exchange services without the need for a VPN connection.

You must have the following prerequisites in order to use the HTTP/RPC feature:

Your workstation is running Windows XP with Service Pack 2 installed (or SP1 with Hotfix Q331320)
Microsoft Outlook 2003 is installed on your workstation
Your workstation has been configured to connect to the Internet

Once these prerequisites are met, do the following:

Go to your Outlook mail settings from Start > Control Panel > Mail.
Click the ‘Show Profiles’ button and press ‘Add’ for a new profile.
Specify your Profile Name and click Next to Add a new e-mail account.
Choose ‘Microsoft Exchange Server’ and go Next.
Specify your Exchange Server Name on the Next page and type your Exchange Mailbox Username.
Click ‘More Settings’ button. If prompted for a password, click Cancel.
Navigate to Connection tab.
Check ‘Connect to my Exchange mailbox using HTTP’ option and click ‘Exchange Proxy Settings’ button
Specify Exchange Proxy Settings:
- Type the URL for your Proxy Server in the 'Use this URL to connect to my proxy server for Exchange' field.
- Make sure that both ‘On fast networks...’ and ‘On slow networks...’ options are checked
- Choose ‘Basic Authentication’ as ‘Proxy Authentication settings’
Press OK, Apply, Next and Finish and OK to save changes.
Start Outlook.
