The RPC over HTTPS protocol allows your full Outlook 2003 MAPI clients to connect to Exchange 2003 Servers using HTTP/HTTPS. This solves the problem remote Outlook 2003 users have when located behind restrictive firewalls.
- Click Start and then right click on the Outlook 2003 icon in the menu. Click on the Properties command.
- Click the Add button in the Mail dialog box.
- Type in a name for the profile in the Profile Name text box. Click OK.
- Select the Add a new e-mail account option in the This wizard will allow you to change the e-mail accounts the direction that Outlook uses page. Click Next.
- On the Server Type page, select the Microsoft Exchange Server option and click Next.
- On the Exchange Server Settings page, type in the FQDN of the front-end Exchange Server. This must be the same name used on the Web site certificate you have assigned to the front-end Exchange Server’s Web site. For example, we obtained a Web site certificate for the front-end Exchange Server’s Web site. The Common Name (CN) on the Web site certificate is UTDEVS08.campus.ad.utdallas.edu. Therefore we enter UTDEVS08.campus.ad.utdallas.edu in the Microsoft Exchange Server text box.
Type a user account name in the User Name text box. Click the Check Name button to confirm that the Outlook 2003 client machine can communicate with the front-end Exchange Server.
Put a checkmark in the Use local copy of Mailbox checkbox.
Click the More Settings button.
- You can change how Outlook detects the connection state on the General tab of the Microsoft Exchange Server dialog box. Do not make any changes here unless you have an explicit reason to do so.
- Click on the Advanced tab. Confirm that there is a checkmark in the Use local copy of Mailbox checkbox. The default selection is Download headers followed by full item.
- Click on the Security tab. Put a checkmark in the Encrypt information checkbox. I am not sure this does anything when you use RPC over HTTP, but encryption is a good thing, so we will enable this checkbox anyhow.
- Click on the Connection tab. Select the Connect using my Local Area Network (LAN) option. Put a checkmark in the Connect to my Exchange mailbox using HTTP, then click the Exchange Proxy Settings button.
- You configure the specifics of the RPC over HTTP session in the Exchange Proxy Settings dialog box. Type in the FQDN to your front-end Exchange Server in the Use this URL to connect to my proxy server for Exchange text box. This is same name listed as the Common Name on the Web site certificate.
Put a checkmark in the Mutually authenticate the session when connecting with SSL checkbox. Put in the FQDN of the front-end Exchange Server (the same name listed on the Web site certificate) in the Principal name for proxy server text box. Use the format:
Msstd:FQDN
For example, we use msstd:webmail.utdallas.edu for our published front-end Exchange Server because the Common Name on the certificate is webmail.utdallas.edu.
Put a checkmark in the Connect using HTTP first, then connect using my Local Area Network (LAN). This is an interesting setting, as its unclear what a "LAN" protocol is in contrast to an "HTTP" protocol. I assume it means to use unencapsulated RPC messages, but I can’t say that for sure.
In the Use this authentication when connecting to my proxy server for Exchange drop down box, select the Basic Authentication option. This forces you to use SSL, which is OK, because we are using SSL for our links.
Click OK on the Exchange Proxy Settings dialog box.
- Click Apply and OK on the Microsoft Exchange Server dialog box.
- Click Next on the Exchange Server Settings page.
- Click Finish on the Congratulations! Page.
- Click OK on the Mail dialog box.
- Open Outlook 2003. You will be able to use HTTPS for the connection, as confirm in the Exchange Server Connection Status window. You can access the connection status window by right clicking on the Outlook 2003 icon in the system tray and selecting the connection status command right after you start up Outlook 2003.
