Apply RPC over HTTP to an existing account

1. If Outlook is open, close it.
2. Click Start then click on Control Panel.
3. If Control Panel is in Category view, click the Switch to Classic View link on the left and then double-click the Mail control panel. If Control Panel is in Classic view, double-click the Mail control panel.
4. Click on the “E-mail Accounts…” button.
5. Select Microsoft Exchange (or whatever is was named). Click on the “Change…” button.
6. Click on the “More Settings…” button. Click the Connection tab.
7. In the Outlook Anywhere section, check the “Connect to Microsoft Exchange using HTTP” box.
8. Click on the “Exchange Proxy Settings…” button.
9. In the “Use this URL to connect to my proxy server for Exchange” box, type the external URL of the proxy server.
10. Make sure the “Connect using SSL only” box is checked.
11. Check the “Only connect to proxy servers that have this principal name in their certificate” box.
12. In the Principle name for proxy server box, type msstd:[external URL] where [external URL] is the external URL of the proxy server.
    Note: Be certain that entries from Step 9 and 12 are correct. Do not have a space before or after the entries. In Step 12, after msstd there is a colon ( : ). It is not a semicolon. The text should be in all lower-case as well.
13. Un-check the “On fast networks, connect using HTTP first, then connect using TCP/IP” box.
14. Check the “On slow networks, connect using HTTP first, then connect using TCP/IP” box.
15. At the bottom of the dialog box, in the Use this authentication when connecting to my proxy server for Exchange list, change the setting from NTLM Authentication to Basic Authentication instead.
16. Click OK. Click Apply. Click OK. Click Next. Click Finish.
    Note: If you get “stuck” at the above step and can’t go forward, you need to double-check the settings in the settings in the Exchange Proxy Settings dialog box.
17. Open Outlook. You will be prompted for a User name and password.
18. In the User name box, type: [domainname]\ where [domainname] is the internal domain name of the network and then username. (i.E. FHN\Administrator)
19. Enter the password for the account. Click OK. In some cases, you may be prompted for the password a second time, please enter it.
20. Outlook should open normally. You’re done.
