Apply RPC over HTTP to an existing account
- If Outlook is open, close it.
- Click Start then click on Control Panel.
- 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.
- Click on the “E-mail Accounts…” button.
- Select Microsoft Exchange (or whatever is was named). Click on the “Change…” button.
- Click on the “More Settings…” button. Click the Connection tab.
- In the Outlook Anywhere section, check the “Connect to Microsoft Exchange using HTTP” box.
- Click on the “Exchange Proxy Settings…” button.
- In the “Use this URL to connect to my proxy server for Exchange” box, type the external URL of the proxy server.
- Make sure the “Connect using SSL only” box is checked.
- Check the “Only connect to proxy servers that have this principal name in their certificate” box.
- 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.
- Un-check the “On fast networks, connect using HTTP first, then connect using TCP/IP” box.
- Check the “On slow networks, connect using HTTP first, then connect using TCP/IP” box.
- 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.
- 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.
- Open Outlook. You will be prompted for a User name and password.
- In the User name box, type: [domainname]\ where [domainname] is the internal domain name of the network and then username. (i.E. FHN\Administrator)
- Enter the password for the account. Click OK. In some cases, you may be prompted for the password a second time, please enter it.
- Outlook should open normally. You’re done.
